I have an application that is creating an new item in Sitecore then opening up the Content Editor to that item, it is loading fine but whenever i try to open the html editor i get a 'NullReferenceException'. This is only happening when i launch the application in this method.
Source Code:
[Serializable]
public class PushToCMS : Command
{
public override void Execute(CommandContext context)
{
//Context.ClientPage.Start(this, "Action_PushToCMS");
Database dbCore = Sitecore.Configuration.Factory.GetDatabase("core");
Item contentEditor = dbCore.GetItem(new ID("{7EADA46B-11E2-4EC1-8C44-BE75784FF105}"));
Database dbMaster = Sitecore.Configuration.Factory.GetDatabase("master");
DatabaseEngines engine = new DatabaseEngines(dbMaster);
Item parentItem = dbMaster.GetItem("/sitecore/content/Home/Events/Parent/");
// Load existing related item if it exists
Event evt = new Event(new Guid(HttpContext.Current.Items["id"].ToString()));
Item item = dbMaster.SelectSingleItem("/sitecore/content/Home/Events/Parent/Item");
if (item == null)
item = CreateNewEvent(engine.DataEngine, parentItem, evt);
Sitecore.Text.UrlString parameters = new Sitecore.Text.UrlString();
parameters.Add("id", item.ID.ToString());
parameters.Add("fo", item.ID.ToString());
Sitecore.Shell.Framework.Windows.RunApplication(contentEditor, contentEditor.Appearance.Icon, contentEditor.DisplayName, parameters.ToString());
}
The only difference i can tell in the loading of the two methods is the url to the html editor, however i dont know where this is being defined or how i can control it.
Launched through normal method:
http://xxxx/sitecore/shell/default.aspx?xmlcontrol=RichTextEditor&da=core&id=%7bDD4372AC-5D37-4C9E-BBFA-C4E3E2A27722%7d&ed=F27055570&vs&la=en&fld=%7b60D10DBB-7CD5-4341-A960-C7AB10347A2C%7d&so&di=0&hdl=H27055699&us=%7b83D34C8A-4CC4-4CD9-A209-600D51B26AAE%7d&mo
Launched through RunApplication:
http://xxxx/layouts/xmlcontrol.aspx?xmlcontrol=RichTextEditor&da=core&id=%7bDD4372AC-5D37-4C9E-BBFA-C4E3E2A27722%7d&ed=F27055196&vs&la=en&fld=%7b60D10DBB-7CD5-4341-A960-C7AB10347A2C%7d&so&di=0&hdl=H27055325&us=%7b83D34C8A-4CC4-4CD9-A209-600D51B26AAE%7d&mo
any help on this would be greatly appreciated.
Phil,
If it is not too late for the answer... :)
It might be the case that you run this code without the permissions to read the core database. In this case, when you try to call contentEditor. you'll get NullReference. I would recommend you using another format of running the application - use another method:
Sitecore.Shell.Framework.Windows.RunApplication("Content Editor", parameters.ToString());
If this doesn't help, please attach the stack trace of the exception you get.
Hope this helps.

I have multiple File Browser Item fields on one page of Application in Oracle Apex.
What happens: When I miss any Item for which validation error fires, I want to hold that file to the browser but I usually loose it if I get that validation error. Is there a solution for the same like other Items fields hold previous value except File Browser Item field. Please see below ss:
Anshul,
APEX 4.2 is very old and no longer supported. A later (or preferably latest) version of APEX will behave differently as Dan explained above.
Can you import your application into apex.oracle.com (which is running APEX 20.1) and you will probably see better results. Based on this you can hopefully use it as justification to upgrade your environment.
Regards,
David
Go to your page-level attributes and a function like the following in the Function and Global Variable Declaration:
function validateItems(request) {
var $file1 = $('#P68_FILE_1');
var $file2 = $('#P68_FILE_2');
var errorsFound = false;
if ($file1.val() === '') {
errorsFound = true;
// Show item in error state
}
if ($file2.val() === '') {
errorsFound = true;
// Show item in error state
}
if (!errorsFound) {
// I think doSubmit was the name of the function back then. If not, try apex.submit
doSubmit(request);
} else {
// Show error message at top of page, I'll use a generic alert for now
alert('You must select a file for each file selector.');
}
}
Then, right-click the Create button and select Create a Dynamic Action. Set the name of the Dynamic Action to Create button clicked.
For the Action, set Type to Execute JavaScript Code. Enter the following JS in code:
validateItems('CREATE');
Finally, ensure that Fire on Initialization is disabled.
Repeat the process for the Save button, but change the request value passed to validateItems to SAVE.
I'd like to reconfigure the default "Publish" menu. The default configuration is this:
I'd like to make Publish the default action, and move it to the top. I'd also like to remove Submit for Moderation, as our site has no current need for that feature.
Ideally, I'd love to be able to override the menu config on a per-app basis - we will likely have other sections of our site in the future where we want a different config.
Is this possible?
This isn't currently possible I'm afraid - the menu items are fixed in wagtailadmin/pages/create.html and edit.html.
This is possible as of Wagtail 2.4 using the register_page_action_menu_item hook, as per Yannic Hamann's answer. Additionally, Wagtail 2.7 (not released at time of writing) provides a construct_page_listing_buttons hook for modifying existing options.
You can add a new item to the action menu by registering a custom menu item with the help of wagtail hooks.
To do so create a file named wagtail_hooks.py within any of your existing Django apps.
from wagtail.core import hooks
from wagtail.admin.action_menu import ActionMenuItem
class GuacamoleMenuItem(ActionMenuItem):
label = "Guacamole"
def get_url(self, request, context):
return "https://www.youtube.com/watch?v=dNJdJIwCF_Y"
#hooks.register('register_page_action_menu_item')
def register_guacamole_menu_item():
return GuacamoleMenuItem(order=10)
Source
If you want to remove an existing menu item:
#hooks.register('construct_page_action_menu')
def remove_submit_to_moderator_option(menu_items, request, context):
menu_items[:] = [item for item in menu_items if item.name != 'action-submit']
The default button SAVE DRAFT is still hardcoded and therefore cannot be configured so easily. See here.
It seems it can't be done on server side without some monkey-patching.
However if you want it for yourself (or have access to computers of those who will publish) you can modify your browser instead.
Install Tampermonkey browser addon
Create new script with a content below
Change http://127.0.0.1:8000/admin/* to your wagtail admin panel url pattern
Save script and check admin panel
Result should look:
// ==UserScript==
// #name Wagtail: replace "Save draft" with "Publish"
// #match *://127.0.0.1:8000/admin/*
// #require https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js
// ==/UserScript==
let $ = window.jQuery;
function modify() {
let draft = $("button.button-longrunning:contains('Save draft')");
let publish = $("button.button-longrunning:contains('Publish')");
if (draft.length && publish.length) {
swap(publish, draft);
}
};
function swap(a, b) {
a = $(a); b = $(b);
var tmp = $('<span>').hide();
a.before(tmp);
b.before(a);
tmp.replaceWith(b);
};
$(document).ready(function() {
setTimeout(function() {
try {
modify();
}
catch (e) {
console.error(e, e.stack);
}
}, 100);
});
Modifying the code above, these selectors works for every admin language:
let draft = $("button.button-longrunning.action-save");
let publish = $("button.button-longrunning[name='action-publish']");
We've been trying to "componentize" our Sitecore solution as we move forward, in prep for transitioning to Page Editor usage (Woot! Finally!), but we're still practically working primarily with Page templates that may be inheritance-based composites of page specific fields, plus 1:many of these componentized templates. An example of how this looks in our solution is below -- Banner Feature Carousel and Featured Cartoon are some of these new components we're creating:
In the interest of trying to move away from using Sitecore.Context.Item (as I was recently reminded by this post) I've started filling in the Datasource template field on the sublayouts for the new components, and it seems like I've got the appropriate connections made between presentation details, the Sitecore sublayout and the .NET code file (as far as I can tell; again, we're newer to working this way).
I've also tried setting up a base class for these components as per this post by Nick Allen, but here's where I'm running into a problem: When I execute my code, this base class is finding the component Sublayout appropriately (the whole "this.Parent as Sublayout" thing) but, when I go to interrogate the Sublayout.Datasource property, it's an empty string. Here's my code (so far) for this base class:
public class ComponentBase : System.Web.UI.UserControl
{
private Sublayout Sublayout { get { return Parent as Sublayout; } }
public Item DataSourceItem
{
get
{
return Sublayout != null && !String.IsNullOrEmpty(Sublayout.DataSource) ?
Sitecore.Context.Database.GetItem(Sublayout.DataSource) : Sitecore.Context.Item;
}
}
}
I'm apparently missing some interplay between the Datasource Template field in the Sitecore sublayout, and how that actually translates to a datasource. Is it because these component templates are being used to compose Page templates? I was thinking that the datasource would just ultimately resolve to the Page template on which the component in question was currently being used, but perhaps that's my misunderstanding.
If anyone could give me any hints of things to check or point me to any resources I might use to get further, I'd appreciate it. I've done quite a bit of asking the Googs, myself, but am just not getting anything that's helping.
Thank you in advance, Sitecore friends!
It looks like you have configured the allowed templates for your sublayout in the steps you describe above. This basically tells Sitecore; 'allow user to select items based on these templates for this sublayout'. This alone does not set up the data source on items using the sublayout. You still need to go into the presentation details for any items using this sublayout, select the sublayout and then set its datasource property (within the content editor go to Presentation > Details > [Sublayout] > Data Source).
My answer to this question gives the source code needed to retrieve the datasource item and to iterate through the sitecore controls on your sublayout setting all of their Item propertys.
Here is the code:
public class SublayoutBase : UserControl
{
private Item _dataSource;
public Item DataSource
{
get
{
if (_dataSource == null)
{
if (Parent is Sublayout)
{
_dataSource =
Sitecore.Context.Database.GetItem(((Sublayout)Parent).DataSource);
}
if (_dataSource == null)
{
_dataSource = Sitecore.Context.Item;
}
}
return _dataSource;
}
}
protected override void OnLoad(EventArgs e)
{
foreach (Control c in Controls)
{
SetFieldRenderers(DataSource, c);
}
base.OnLoad(e);
}
private void SetFieldRenderers(Item item, Control control)
{
if (item != null)
{
var ctrl = control as Sitecore.Web.UI.WebControl;
if (ctrl != null && !string.IsNullOrEmpty(ctrl.DataSource))
{
//don't set the source item if the DataSource has already been set.
return;
}
if (control is FieldRenderer)
{
var fr = (FieldRenderer)control;
fr.Item = item;
}
else if (control is Image)
{
var img = (Image)control;
img.Item = item;
}
else if (control is Link)
{
var link = (Link)control;
link.Item = item;
}
else if (control is Text)
{
var text = (Text)control;
text.Item = item;
}
else
{
foreach (Control childControl in control.Controls)
{
SetFieldRenderers(item, childControl);
}
}
}
}
}
When you start using sublayouts on which you will set your datasource try to use the marketplace "Sublayout Parameter Helper". When you use the class they provide as base class and have set everything up right in your Sitecore Environment you will find yourself having a "this.DatasourceItem" -> which will contain your datasource Item, or the context Item if none is given.
http://marketplace.sitecore.net/en/Modules/Sub_Layout_Parameter_Helper.aspx
To find out more on how datasource works, try searching on http://sdn.sitecore.net. There is alot of documentation available that should get you in the right direction. Generally it will be enough to just add a datasource in the sublayout that you can access in your sublayout.
When you read a datasource from a sublayout all it will do is check if the datasource field on that sublayout is filled and will return you information regarding this datasource. So when you add a new component to a page using the page editor (for example a sublayout for a news article) and you have a datasource template defined and filled in during adding this components, you will see that when you check the presentation details on that page a sublyaout with a datasource has been added. The datasource will point to a folder in which you will find an item based on the datasource template you specified on your sublayout. You should also double check this, cause if no datasource is present on the added sublayout it will be obvious you can't access it from your code.
If you are using Sitecore 7 update 1 you can actually now use the attributes. From the Release Notes:
To make it easier to get the data source for a sublayout from
code-behind, the data source is now transferred to the sublayout
control in a "sc_datasource" attribute. (320768)
To get the data source from code, simply refer to
this.Attributes["sc_datasource"];
I am developing a mobile application in which I want to use a list which contains 400 rows. I got data from Sqlite database. When I run the application and click the button for the list, the list view is loading so slowly and takes about 45 seconds. I also tried getting data from an arraycollection inside the application but I had same problem. Is this normal? Any idea or advice for this issue?
sqlStat.text="SELECT City FROM Cities";
sqlStat.execute();
dataArray=sqlStat.getResult().data;
appModel=AppModel.getInstance();
if(appModel.cities == null)
{
appModel.cities = new ArrayCollection();
var obj:Object;
for( var i:int=0; i<dataArray.length; i++ )
{
obj = new Object();
obj.Name = dataArray[i].City
appModel.cities.addItem(obj);
}
myList.dataProvider=appModel.cities;
}
The OP wrote:
I solved my problem. ListForm component causes renderer problem. I used List component instead of that and created arrayCollection dataprovider for my list inside my class. It works faster than previous.
I am creating a custom item editor, and am using the following blog post as a reference for responding to the "save" event in the Content Editor, so that I do not need to create a second, confusing Save button for my users.
http://www.markvanaalst.com/sitecore/creating-a-item-editor/
I am able to save my values to the item, but the values in the normal Content tab are also being saved, overriding my values. I have confirmed this via Firebug. Is there a way to prevent this, or to ensure my save is always after the default save?
I have this in as a support ticket and on SDN as well, but wondering what the SO community can come up with.
Thanks!
Took a shot at an iframe-based solution, which uses an IFrame field to read and save the values being entered in my item editor. It needs to be cleaned up a bit, and feels like an interface hack, but it seems to be working at the moment.
In my item editor:
jQuery(function () {
var parentScForm = window.parent.scForm;
parentScForm.myItemEditor = window;
});
function myGetValue(field) {
var values = [];
jQuery('#myForm input[#name="' + field + '"]:checked').each(function () {
values.push(jQuery(this).val());
});
var value = values.join('|');
return value;
}
In my Iframe field:
function scGetFrameValue() {
var parentScForm = window.parent.scForm;
if (typeof (parentScForm.myItemEditor) != "undefined") {
if (typeof (parentScForm.myItemEditor.myGetValue) != "undefined") {
return parentScForm.myItemEditor.myGetValue("myLists");
}
}
return null;
}
In theory, I could have multiple fields on the item which are "delegated" to the item editor in this way -- working with the content editor save rather than trying to fight against it. I'm a little uneasy about "hitchhiking" onto the scForm to communicate between my pages -- might consult with our resident Javascript hacker on a better method.
Any comments on the solution?
