I am new at Camunda and just started learning. I am trying to populate a drop down list at the startEvent. I have the drop down in the embedded form like this.
<select cam-variable-name="PRODUCT_TYPE"
cam-variable-type="String"
cam-choices="AVAILABLE_PRODUCT_TYPES">
</select>
I do not know where to implement the java delegate with a code that should look similar to this.
Map<String, String> productTypes = new HashMap<String, String>();
productTypes.put("001", "Notebook");
productTypes.put("002", "Server");
productTypes.put("003", "Workstation");
execution.setVariable("AVAILABLE_PRODUCT_TYPES",
objectValue(customerData)
.serializationDataFormat(SerializationDataFormats.JSON)
.create());
Listeners do not work for startEvent. I have tried camunda:formHandlerClass extension. That did get invoked but it resulted in a blank form being printed since createStartFormData was returning null.
Please point me in the right direction.
You can set a listener with the above code on the Process itself like

Sorry for the newbie question. Learning Apex here. Been working on an issue for several hours and can't seem to needle it out.
I have a JSON that I need converted to a List... the JSON is retrieved via an API. The code is pretty simple, it is only a couple of lines.
The JSON looks like this:
{"id":1,"abbreviation":"ATL","city":"Atlanta","conference":"East","division":"Southeast","full_name":"Atlanta Hawks","name":"Hawks"}
And the code I am told to use to retrieve it looks like this:
Map<String, Object> resultsMap = (Map<String, Object>) JSON.deserializeUntyped(results.getBody());
Based on the JSON provided, there does not appear to be a MAP key being assigned, so I have no idea how to get it so that I may assign it to a List...
I've already tried assigning it directly to a List, but I didn't get much success there either.
I've tried this already:
List<Object> other = (List<Object>) results.get('');
I've also tried this:
List<Object> other = (List<Object>) results.keySet()[0];
I'm sure it is something simple. Any help would be appreciated.
Thanks
You cant convert the map to a list without an id. Alternatively why to convert it to List. Use the map itself. Below is a code example of how you can use it using your JSON response. For example, I want to insert this JSON response into the contact record, so I can map it using the MAP itself.:
#RestResource(urlMapping='/URIId/*')
global class OwneriCRM {
#HttpPut
global static String UpdateOwnerinfo(){
RestRequest req= RestContext.request;
RestResponse res= RestContext.response;
res.addHeader('Content-type','application/JSON');
Map<String,Object> responseresult=new Map<String,Object>();
Map<String,Object> results= (Map<String,Object>)JSON.deserializeUntyped(req.requestBody.toString());
List<contact> insertList = new List<contact>();
for (String key : results.keySet()){
System.debug(results.get(key));
contact c= new contact();
c.ContactField__C = results.get(id);
c.ContactField1__C = results.get(city);
c.ContactField2__C = results.get(conference);
c.ContactField3__C = results.get(division);
c.ContactField3__C = results.get(full_name);
c.ContactField3__C = results.get(name);
insertList.add(c);
}
if(!insertList.Isempty()){
update insertList;
}
Question can be disregarded. Not sure if there is a way to withdraw the question.
Question was based on the fact that previous APIs had been sent in the following format:
{"data": {"more stuff": "stuff"} }
And the map key was 'data' with a list. In this scenario, the whole API was a list and the keys to the map were set in place with the actual values instead.
I have defined simple one-to-many relationship as:
#Relationship(type = "BELONG")
private Set<Category> categories;
I want to query all the objects based on the exact set of Category. i.e. implement something like:
Page<SomeObject> findAllByCategories(Set<Category> categories, PageRequest page);
What is the best way to do it in Spring Data Neo4j?
You have a couple of options on how you can do this.
Your calling code can simply call the following on your SomeObjectRepository:
Iterable<Long> ids = categories.stream().map(SomeObject::getId).collect(Collectors.toSet());
Iterable<SomeObject> someObjects = someObjectRepository.findAll(ids, 1);
Note this method does not support paging though.
Another way is to inject a Session into your calling code and either write a custom Cypher query to retrieve the objects you want or use the load all by instance method:
#Autowired
private Session session;
...
// Option 1: write some cypher
Map<String, Object> params = new HashMap<>():
params.put("ids", ids) // use a stream like above to collect the ids.
Iterable<SomeObject> someObjects = session.query(SomeObject.class, "MATCH (n:SomeObject) ...", params);
//Option 2: use the load by instances method which also allows pagination:
Collection<SomeObject> someObjects = session.loadAll(categories, new Pagination(0, 25));
My recommendation would be option 2 as it pretty much does exactly what you want.
Is there any way to parametise the Datasource for the 'source' field in the Template Builder?
We have a multisite setup. As part of this it would save a lot of time and irritation if we could point our Droptrees and Treelists point at the appropriate locations rather than common parents.
For instance:
Content
--Site1
--Data
--Site2
--Data
Instead of having to point our site at the root Content folder I want to point it at the individual data folders, so I want to do something like:
DataSource=/sitecore/content/$sitename/Data
I can't find any articles on this. Is it something that's possible?
Not by default, but you can use this technique to code your datasources:
http://newguid.net/sitecore/2013/coded-field-datasources-in-sitecore/
You could possibly use relative paths if it fits with the rest of your site structure. It could be as simple as:
./Data
But if the fields are on random items all over the tree, that might not be helpul.
Otherwise try looking at:
How to use sitecore query in datasource location? (dynamic datasouce)
You might want to look at using a Querable Datasource Location and plugging into the getRenderingDatasource pipeline.
It's really going to depend on your use cases. The thing I like about this solution is there is no need to create a whole bunch of controls which effectively do he same thing as the default Sitecore ones, and you don't have to individually code up each datasource you require - just set the query you need to get the data. You can also just set the datasource query in the __standard values for the templates.
This is very similar to Holger's suggestion, I just think this code is neater :)
Since Sitecore 7 requires VS 2012 and our company isn't going to upgrade any time soon I was forced to find a Sitecore 6 solution to this.
Drawing on this article and this one I came up with this solution.
public class SCWTreeList : TreeList
{
protected override void OnLoad(EventArgs e)
{
if (!String.IsNullOrEmpty(Source))
this.Source = SourceQuery.Resolve(SContext.ContentDatabase.Items[ItemID], Source);
base.OnLoad(e);
}
}
This creates a custom TreeList control and passes it's Source field through to a class to handle it. All that class needs to do is resolve anything you have in the Source field into a sitecore query path which can then be reassigned to the source field. This will then go on to be handled by Sitecore's own query engine.
So for our multi-site solution it enabled paths such as this:
{A588F1CE-3BB7-46FA-AFF1-3918E8925E09}/$sitename
To resolve to paths such as this:
/sitecore/medialibrary/Product Images/Site2
Our controls will then only show items for the correct site.
This is the method that handles resolving the GUIDs and tokens:
public static string Resolve(Item item, string query)
{
// Resolve tokens
if (query.Contains("$"))
{
MatchCollection matches = Regex.Matches(query, "\\$[a-z]+");
foreach (Match match in matches)
query = query.Replace(match.Value, ResolveToken(item, match.Value));
}
// Resolve GUIDs.
MatchCollection guidMatches = Regex.Matches(query, "^{[a-zA-Z0-9-]+}");
foreach (Match match in guidMatches)
{
Guid guid = Guid.Parse(match.Value);
Item queryItem = SContext.ContentDatabase.GetItem(new ID(guid));
if (item != null)
query = query.Replace(match.Value, queryItem.Paths.FullPath);
}
return query;
}
Token handling below, as you can see it requires that any item using the $siteref token is inside an Site Folder item that we created. That allows us to use a field which contains the name that all of our multi-site content folders must follow - Site Reference. As long at that naming convention is obeyed it allows us to reference folders within the media library or any other shared content within Sitecore.
static string ResolveToken(Item root, string token)
{
switch (token)
{
case "$siteref":
string sRef = string.Empty;
Item siteFolder = root.Axes.GetAncestors().First(x => x.TemplateID.Guid == TemplateKeys.CMS.SiteFolder);
if (siteFolder != null)
sRef = siteFolder.Fields["Site Reference"].Value;
return sRef;
}
throw new Exception("Token '" + token + "' is not recognised. Please disable wishful thinking and try again.");
}
So far this works for TreeLists, DropTrees and DropLists. It would be nice to get it working with DropLinks but this method does not seem to work.
This feels like scratching the surface, I'm sure there's a lot more you could do with this approach.
Trying to become a grails convert I have begun converting an existing application to Grails and Groovy. It works very well but I get stuck on the conversion of select tags.
I have a domain class:
package todo
class Person {
String ssn
String firstname
String familyname
String role
String emailname
String emailserver
...
When creating a new "todo" task an owner may be assigned from those persons in the system who are developers and I get this working (a fairly direct translation from PHP):
<select id="owner" name="owner">
<option>Noboby ...</option>
<g:each in="${Person.list()}">
<g:if test="${it?.role=='developer'}">
<option value="${it?.id}">${it?.firstname} ${it?.familyname}</option>
</g:if>
</g:each>
</select>
But every attempt to make it more "Grails-ish" fails. How can it be moulded into Grails v2.2.1 code? I spent hours reading, trying, failing.
If you woulkd like to make it more Grails style, you should perform all your logic within controllers \ services not in the view.
Assuming you have a view createTodo in the folder person and the PersonController, then modify your createTodo action like this:
class PersonController {
def createTodo() {
def developers = Person.findAllWhere(role: 'developer')
[developers: developers, ... /* your other values */]
}
}
So you don't need to handle with database operations in your view.
Next step is to use the g:select tag like this:
<g:select name="owner" from="${developers}" optionValue="${{'${it.firstName} ${it.familyName}'}}" noSelection="['null':'Nobody ...']" optionKey="id" value="${personInstance?.id}" />
Try this code:
<g:select optionKey="id" from="${Person.findAllByRole('developer')}" optionValue="${{it.fullName}}" value="${yourDomainInstance?.person?.id}" noSelection="['null':'Nobody']"></g:select>
And in your class:
class Person {
....
String getFullName(){
it?.firstname+' '+ it?.familyname
}
static transients = ['fullName']
....
}
See g:select tag for more details
Finally, I got it working as I want to and it works (almost) according to the #"Mr. Cat" solution. One little detail, though, 'it' does not exist in the class so the getFullName method had to become:
String getFullName(){
this?.firstname+' '+ this?.familyname
}
Up and working, thank you for all help.
my question is basically the same as #Bob Black's Cannot access sitecore item field via API but I agree with #techphoria414 that the accepted solution is not necessary and in my case does not work.
In my own words, I have a template Departure that I have been using for about a year now creating and updating items programmatically. I have added a new field Ship to the template. When I create a new item the field comes up as null when I try to access it using departure.Fields["Ship"]. If I step over the line causing the exception then after calling departure.Editing.EndEdit() I can then see the Ship field if I call departure.Fields.ToList(). If I add the template to a content item via the Sitecore GUI I can see the field and use it, and if I look at a content item which is based on the template I can see the new field too. So it is only when I access the template/item programmatically that it is null.
I have sitecore running on my local machine with a local sqlserver, and publish to my local machine.
Here is my code
String ship = "MSDisaster";
foreach (Language language in SiteLanguages)
{
departure = departure.Database.GetItem(departure.ID, language);
departure.Editing.BeginEdit();
try
{
departure.Fields["StartDate"].Value = GetSitecoreDateString(xDep, "StartDate");
departure.Fields["EndDate"].Value = GetSitecoreDateString(xDep, "EndDate");
departure.Fields["Guaranteed"].Value = xDep.SelectSingleNode("./Guaranteed").InnerText;
departure.Fields["Status"].Value = xDep.SelectSingleNode("./Status").InnerText;
departure.Fields["Currency"].Value = ConvertLanguageToCurrency(language);
departure.Fields["Market"].Value = ConvertLanguageToMarket(language);
departure.Fields["TwinSharePrice"].Value = GetPrice(xDep, "twn", language);
departure.Fields["SinglePrice"].Value = GetPrice(xDep, "sgl", language);
if (!String.IsNullOrEmpty(ship))
departures.Fields["Ship"].Value = ship;
}
catch (Exception ex)
{
departure.Editing.CancelEdit();
log.Error(ex);
throw ex;
}
departure.Editing.EndEdit();
}
So, how do I get the field be picked up?
Thanks,
James.
Firstly do you see the field in the web database in the sitecore administration.
If you do the item has the fields, you then should check the template assigned on the item and double check that the field is actually called "ship" and check the case as ive seen this as an issue before.
Also check the security on the item and field just in case anyone changed anything.
Next try and get the data from the item but instead of using the field name, use the field ID.
Let me know how you go?
Chris
Sorry Chris, StackOverflow, and the others who looked at my questions. It was a stupid typo. It's even there in my question
departure.Fields["SinglePrice"].Value = GetPrice(xDep, "sgl", language);
if (!String.IsNullOrEmpty(ship))
departures.Fields["Ship"].Value = ship;
}
departure is the item I am working on, departures is the collection it belongs to... doh.
So what is the protocol here? Do I delete my question now because it isn't really going to help anyone code better?
James.
