Error resolving URL's that do not have a space - sitecore

Currently in an effort to upgrade our site from 7.2 to 8.2 161115 and getting a Document Not Found error if a URL does not have a space in it.
Almost all of the URL's in our site have a space in the content item name and work fine. Only a few don't.
For example these work:
/Page Name/
/Page-Name/
/Page/Sub Page/
/Page/Sub-Page/
These do not work:
/Page
/Page/SecondaryPage
This error occurs on a special template we have called "Context Resolver" which forwards a visitor to a different page based on rules. The template has three fields:
Forwarding Enabled (checkbox)
Rules (ruleset)
Default Item (droptree)
The idea is that these items make decisions on where to send a visitor. We have a pipeline that runs the following code:
public override void Process(HttpRequestArgs args)
{
if (args == null) return;
var item = Sitecore.Context.Item;
if (item == null) return;
if (item.TemplateID != SitecoreDefinitions.ContextForwarderTemplate) return;
if (!item.IsContextForwarderEnabled()) return;
var rulesItem = item.Fields["Rules"];
if (rulesItem != null)
{
RuleFactory.InvalidateCache();
var rules = RuleFactory.GetRules<RuleContext>(rulesItem);
if (sitecoreRepository.ExecuteRules(rules.Rules))
return;
}
ReferenceField refItem = item.Fields["Context"];
Context.Item = refItem.TargetItem;
}
This work's great, as expected from our previous 7.2 site on any URL with a space. If there is no space, it fails. Without the rules, there is no difference, so the error is happening from this line:
Sitecore.Context.Item = someNewItem
Thoughts? We can easily reproduce this issue with this template type on the working URL's by removing the space, and add a space on failing URL's to make them work.

Sitecore display name url does not work without language code

On this Sitecore website (6.5.0 rev. 120706), I have this sitecore item called XYZ. So I have http://example.com/XYZ/.
I've added french localization, so using display names I now have:
http://example.com/XYZ-en/
http://example.com/XYZ-fr/
The english version works well, but the french does not and resolves to 404 unless I go to the english first, click on my language switcher button first. When I click on it, I'm redirected to http://example.com/fr-CA/XYZ-fr/, which works. From then on, the english url stops working, the french one works. As I switch languages like that, I always only have one of the two that work.
That button runs this code:
protected void LanguageLinkClick(object sender, EventArgs e)
{
var lang = (Sitecore.Context.Language.Name == "en") ? "fr-ca" : "en";
Tools.RedirectToLanguage(lang, Response);
}
That Tools function runs the following code:
public static void RedirectToLanguage(string pStrLangToSet, HttpResponse pResponse)
{
if (!string.IsNullOrEmpty(pStrLangToSet))
{
var newLang = Language.Parse(pStrLangToSet);
if (newLang != null)
{
Sitecore.Context.SetLanguage(newLang, true);
var itm = Sitecore.Context.Item;
if (Sitecore.Context.Item != null)
{
var itemInLang = Sitecore.Context.Database.Items[itm.ID, newLang];
if (itemInLang != null)
{
pResponse.Redirect(BuildUrl(itemInLang));
}
}
}
}
}
This is somewhat old code that is in this old project.
Is there anything I should look for that would intercept default display name behavior? Or isthis behavior with display names something that's not managed out of the box?
Thanks for any help!
This is the expected behaviour. This article from John West describes the steps involved in the language resolving process and details of the ItemResolver process can be found here.
What I assume you have set in the LinkProvider for your site is useDisplayName=true and maybe languageEmbedding=false, something like the following:
<add name="sitecore" type="Sitecore.Links.LinkProvider, Sitecore.Kernel"
alwaysIncludeServerUrl="false" addAspxExtension="true" encodeNames="true"
languageLocation="filePath" lowercaseUrls="false" shortenUrls="true"
languageEmbedding="never" useDisplayName="true" />
This tells the LinkManager to build URLs using the display name of the Item, hence you have multilingual URLs. Your RedirectToLanguage method switches the context language, from EN to FR-CA and vice versa, which puts Sitecore into that specific language mode for the user.
The following pipeline in <httpRequestBegin> tries to resolve an Item from your requested URL:
<processor type="Sitecore.Pipelines.HttpRequest.ItemResolver, Sitecore.Kernel" />
And one of the attempts in that method is to ResolveUsingDisplayName(args). So it will be trying to resolve an Item with an EN display name, but the Context Language is set to FR-CA so in fact it will never find the item, hence the 404.
You have 2 options here:
Set languageEmbedding="always" in your LinkProvider, which mean your URLs will be formatted like "/en/Nice-Product-With-Lots-Of-Options" and "/fr-ca/Mon-Produit-Avec-Plusieurs-Options".
Add a custom pipeline processor after the default ItemResolver which tries to resolve using the alternate language, and if it finds a match sets the Context Item and switches language.
The following will call the default Sitecore ItemResolver after you switch to the alternate language and then attempt to resolve, which will try to find the Item using display name:
public class AlternateLanguageItemResolver : HttpRequestProcessor
{
public override void Process(HttpRequestArgs args)
{
Assert.ArgumentNotNull(args, "args");
if (Context.Item != null || Context.Database == null || args.Url.ItemPath.Length == 0)
return;
var origLanguage = Sitecore.Context.Language;
Sitecore.Context.Language = AltLanguage;
// try to find it using default ItemResolver with alternate language
var itemResolver = new Sitecore.Pipelines.HttpRequest.ItemResolver();
itemResolver.Process(args);
if (Context.Item == null)
{
// well we didn't find it, so switch the context back so everyting can continue as normal
Sitecore.Context.Language = origLanguage;
return;
}
// We found the Item! Switch the User Language for future requests
Sitecore.Context.SetLanguage(AltLanguage, true);
}
private Language _altLanguage = null;
private Language AltLanguage
{
get
{
if (_altLanguage == null)
{
var altLang = (Sitecore.Context.Language.Name == "en") ? "fr-ca" : "en";
_altLanguage = Language.Parse(altLang);
}
return _altLanguage;
}
}
}
And patch it in after the default ItemResolver:
<processor type="Sitecore.Sample.AlternateLanguageItemResolver, Sitecore.Sample"
patch:after="processor[#type='Sitecore.Pipelines.HttpRequest.ItemResolver, Sitecore.Kernel']"/>
This is an untested prototype, check that subsequent requests are returned in the correct switched language. Otherwise redirect back to itself like you in your original code.
So if I understand correctly you'd like these urls to resolve the language for you:
http://example.com/XYZ-en/
http://example.com/XYZ-fr/
The LanguageResolver will resolve the language in this order:
1. language can be distilled from the url (cannot be done with above urls)
2. a language cookie is available for this site (sitename#lang)
3. fall back to default configured language
When you switch, using your switcher, the url paths start with the language code, then the resolver is able to resolve the language by url and persists the language in the language cookie. This is why you experience this behavior of one working language at a time.
The best you can do is always use language in urls (linkprovider configuration), otherwise you'd have to hook in the languageresolver and do some funky check on displayname for each language, but that will probably get very expensive.

Sitecore Url works with any Extension

In my website , the url's are working even entering something after .aspx and giving staus code 200.
Eg: below is normal page with .aspx and status code 200.
But even i have any random extension i got 200 status code which suppossed to be a 404 Status code,
Any Help.
Sitecore is quite generous when it resolves URL's. If you want to enforce correct extensions, you could create a custom Item Resolver which ensures the context item remains null in the process method if the URL has the incorrect extension.
Here's a helpful article on creating an Item Resolver:
Thoughts on httpRequestBegin - Custom Item Lookups
In my example below, the base process method is called. After that we check if the Context Item meets the requirements, and set it to null if not. (You'll need to implement TemplateIsAPageType and ExtensionIsValid as you see fit.)
public class CustomItemResolver : HttpRequestProcessor
{
public override void Process( HttpRequestArgs args )
{
base.Process(args);
if( Context.Item != null && TemplateIsAPageType() && !ExtensionIsValid())
{
Context.Item = null;
}
}
}
Another approach might be something like this, where we compare the requested URL with the resolved item's 'ideal' URL:
public class CustomItemResolver : HttpRequestProcessor
{
public override void Process( HttpRequestArgs args )
{
base.Process(args);
if( Context.Item == null)
return;
var requestUrl = HttpContext.Current.Request.RawUrl;
var idealUrl = LinkManager.GetItemUrl(Context.Item);
if(requestUrl != idealUrl)
Context.Item = null;
}
}
Sitecore skips everything after the last dot ”.” in an url when attempting to resolve an item.
This is done by the class Sitecore.Web.RequestUrl which has a property called ItemPath. This property attempts to create a valid path to an item from the requested url. It is not possible to override this property.
If you for some reason would like Sitecore to return a 404 status code if an item is requested with a file extension, such as .aspx, you could do something like this in a 404 not found item resolver. See this post http://laubplusco.net/handling-404-sitecore-avoid-302-redirects/ the following method extends the one shown in the post.
protected virtual bool IsValidContextItemResolved(string filePath)
{
if (Context.Item == null || !Context.Item.HasContextLanguage())
return false;
if (filePath.Contains(".") && !RequestIsForPhysicalFile(filePath))
return false;
return !(Context.Item.Visualization.Layout == null
&& string.IsNullOrEmpty(WebUtil.GetQueryString("sc_layout")));
}
It is important to ensure that the requested url is not for a physical file first. This is done by checking that the args.Url.filepath does not map to a physical file.
The rule which I show here says that if an item has been resolved and the filepath contains a dot then the requested url should return a 404 and the context item should be the not found item. The code could be extended to check what comes after the dot to see if it is a valid extension.

Can Glass.Mapper V3 support language fallback (field-level and item-level)?

We just updated our project to use Glass.Mapper V3. We LOVE it. But we've encountered an issue. It doesn't seem to respect language fallback.
We have our site set up so that if a user picks a non-default language, they will see the item of that language if it exists. If not, they will see the default ("fallback") language version. We have also set this up at the field level, so that if there is a non-default version of an item but not all the fields are changed, any unchanged fields will fall back to the default language version's value for that field.
Is there anything we can do to enable Glass to use language fallback?
I am updating this with a bit of background on why we do the check. If you ask for a Sitecore item that doesn't exist you get a null value, so that is simple to handle. However if you ask for a Sitecore item that doesn't exist in that particular language returns an item with no versions. This means we have to do this check because otherwise Glass would end up returning empty class which I don't think makes much sense.
This answer will get a little experimental.
First in the the Spherical.cs file you need to disable the check:
protected void Application_BeginRequest()
{
Sitecore.Context.Items["Disable"] = new VersionCountDisabler();
}
We can then move the check to later on to the Object Construction pipeline. First create a task:
public class FallbackCheckTask : IObjectConstructionTask
{
public void Execute(ObjectConstructionArgs args)
{
if (args.Result == null)
{
var scContext = args.AbstractTypeCreationContext as SitecoreTypeCreationContext;
if (scContext.Item == null)
{
args.AbortPipeline();
return;
}
//this checks to see if the item was created by the fallback module
if (scContext.Item is Sitecore.Data.Managers.StubItem)
{
return;
}
// we could be trying to convert rendering parameters to a glass model, and if so, just return.
if (String.Compare(scContext.Item.Paths.FullPath, "[orphan]/renderingParameters", true) == 0)
{
return;
}
if (scContext.Item.Versions.Count == 0)
{
args.AbortPipeline();
return;
}
}
}
}
Then finally register this task in the GlassMapperScCustom class:
public static void CastleConfig(IWindsorContainer container){
var config = new Config();
container.Register(
Component.For<IObjectConstructionTask>().ImplementedBy<FallbackCheckTask>().LifestyleTransient()
);
container.Install(new SitecoreInstaller(config));
}
I haven't tested this but it should in theory work <- disclaimer ;-)
There are few potential issues with provided solution when sitecore 7 (7.2) + IoC + solr + mvc is used.
When using IoC ex Winsdor please make sure that your Global.asax looks like this one <%# Application Codebehind="Global.asax.cs" Inherits="Sitecore.ContentSearch.SolrProvider.CastleWindsorIntegration.WindsorApplication" Language="C#" %>. Once, by mistake this file has been changed to <%# Application Codebehind="Global.asax.cs" Inherits="Merck.Manuals.Web.Global" Language="C#" %> and language fallback was not working. Also the errors we were getting wasn't descriptive as we thought that solr schema is incorrect.
Code Sitecore.Context.Items["Disable"] = new VersionCountDisabler(); can be added to PreprocessRequestProcessor and it works fine which is better solution that modifying global.asax.

Set queryable source on Rendering Parameter Template field

I have a Rendering Parameter template applied to a sublayout. It has a single Droptree field on it, and I want to set the Source of that field to a Sitecore query so I can limit the options available for that field.
Source can be:
query:./*
or
query:./ancestor-or-self::*[##templatename='MyTemplate']/
The query just needs to grab items relative to the content item that we're on. This normally works with Droptree fields in the content editor.
However I'm finding that the query isn't working here because we're in the rendering parameters, so it's not using the content item as it's context.
The query fails and I just get the full Sitecore tree.
I found this can be fixed up for the Datasource field with 'Queryable Datasource Locations' at this link:-
http://www.cognifide.com/blogs/sitecore/reduce-multisite-chaos-with-sitecore-queries/
However I don't know where to start to get this working for other rendering parameter fields.
Any ideas? (I'm using Sitecore 6.6 Update 5)
Unfortunately, the pipeline mentioned in Adam Najmanowicz's answer works for some other types, like Droplink and Multilist, but the pipeline isn't run for Droptree fields.
After looking into this deeper I found that the Source of a Droptree field IS using the wrong context item, as Adam mentioned, but the code comes from the Droptree field itself:-
Sitecore.Shell.Applications.ContentEditor.Tree, Sitecore.Kernel
Utilising the query string code from Adam's answer, we can create a 'fixed' Droptree custom field, that is almost the same as the regular Droptree but will use the correct context item instead.
The code will inherit from the normal Tree control, and only change the way that the Source property is set.
public class QueryableTree : Sitecore.Shell.Applications.ContentEditor.Tree
{
// override the Source property from the base class
public new string Source
{
get
{
return StringUtil.GetString(new string[]
{
base.Source // slightly altered from the original
});
}
set
{
Assert.ArgumentNotNull(value, "value");
if (!value.StartsWith("query:", StringComparison.InvariantCulture))
{
base.Source = value; // slightly altered from the original
return;
}
Item item = Client.ContentDatabase.GetItem(this.ItemID);
// Added code that figures out if we're looking at rendering parameters,
// and if so, figures out what the context item actually is.
string url = WebUtil.GetQueryString();
if (!string.IsNullOrWhiteSpace(url) && url.Contains("hdl"))
{
FieldEditorParameters parameters = FieldEditorOptions.Parse(new UrlString(url)).Parameters;
var currentItemId = parameters["contentitem"];
if (!string.IsNullOrEmpty(currentItemId))
{
Sitecore.Data.ItemUri contentItemUri = new Sitecore.Data.ItemUri(currentItemId);
item = Sitecore.Data.Database.GetItem(contentItemUri);
}
}
if (item == null)
{
return;
}
Item item2 = item.Axes.SelectSingleItem(value.Substring("query:".Length));
if (item2 == null)
{
return;
}
base.Source = item2.ID.ToString(); // slightly altered from the original
}
}
The above code is pretty much the same as the Source property on the base Tree field, except that we figure out the proper context item from the URL if we've detected that we're in the rendering parameters dialog.
To create the custom field, you just need to edit the Web.Config file as described here. Then add the custom field to the core database as described here.
This means that parameters can now have queries for their source, allowing us to limit the available items to the content editor. (Useful for multi-site solutions).
The key here would be to set the Field Editor's context to be relative to the item you are editing instead of the Rendering parameters (that I think it has by default).
So you could have processor:
public class ResolveRelativeQuerySource
{
public void Process(GetLookupSourceItemsArgs args)
{
Assert.IsNotNull(args, "args");
if (!args.Source.StartsWith("query:"))
return;
Item contextItem = null;
string url = WebUtil.GetQueryString();
if (!string.IsNullOrWhiteSpace(url) && url.Contains("hdl"))
{
FieldEditorParameters parameters = FieldEditorOptions.Parse(new UrlString(url)).Parameters;
var currentItemId = parameters["contentitem"];
if (!string.IsNullOrEmpty(currentItemId))
{
Sitecore.Data.ItemUri contentItemUri = new Sitecore.Data.ItemUri(currentItemId);
contextItem = Sitecore.Data.Database.GetItem(contentItemUri);
}
}
else
{
contextItem = args.Item;
}
}
}
hooked as:
<sitecore>
<pipelines>
<getLookupSourceItems>
<processor patch:before="*[#type='Sitecore.Pipelines.GetLookupSourceItems.ProcessQuerySource, Sitecore.Kernel']"
type="Cognifide.SiteCore.Logic.Processors.ResolveRelativeQuerySource, Cognifide.SiteCore" />
</getLookupSourceItems>
</pipelines>
</sitecore>
Together with ResolveQueryableDatasources from Przemek's blog this should solve your problem.

Sitecore: How to get Item's Alias Url

Is it possible to get the Alias url of an Item from .NET? I am able to use Sitecore.Links.LinkProvider class to get the item's default url, but I haven't found a way to get the Alias url.
I don't think there's a method built into the Sitecore API anywhere that does that, but you could try something like this ...
string query = String.Format("/*/system/Aliases//*[##templateid='{0}' and contains(#Linked item, '{1}')]", Sitecore.TemplateIDs.Alias, Sitecore.Context.Item.ID);
Sitecore.Data.Items.Item alias = Sitecore.Context.Database.SelectSingleItem(query);
string aliasUrl = string.Empty;
if (alias != null) {
aliasUrl = String.Format("/{0}.aspx", alias.Name);
}
(I have not tested this, it's based on some code I'm already using + some other stuff off the top of my head.)
