Several identical elements in <extensionElements> tag [message #1744359]

Hi there!

Is it possible to add several identical elements to the <extensionElements> tag without the intermediate container tag (like "TaskConfig" in DeveloperTutorial's example)?

My current goal is to add several taskListener elements with different event types to my customTask. It should turn out as in TaskListenerTest example from Activiti repository e.g.:

<userTask id="task1" name="Schedule meeting" > 
	<documentation> 
		Schedule a meeting with management. 
	</documentation> 
	<extensionElements> 
		<activiti:taskListener event="create" class="org.activiti.examples.bpmn.tasklistener.TaskCreateListener" /> 
		<activiti:taskListener event="complete" class="org.activiti.examples.bpmn.tasklistener.TaskCompleteListener"> 
			<activiti:field name="greeter" stringValue="The Process" /> 
			<activiti:field name="shortName" expression="${'Activiti'.substring(0,3)}" /> 
		</activiti:taskListener> 
		<activiti:taskListener event="assignment" class="org.activiti.examples.bpmn.tasklistener.TaskAssignmentListener" /> 
		<activiti:taskListener event="all" class="org.activiti.examples.bpmn.tasklistener.TaskAllEventsListener" /> 
	</extensionElements>
</userTask>

I can fetch all TaskListener extension objects from current Task by calling:

ModelDecorator.getAllExtensionAttrivuteValues(eObject, TaskListener.class);

But I don't see any way to save more than one of newly created TaskListener objects directly to the extensionElements container because there is only one corresponding EStructuralFeature object for my taskListener tag.

Hi all once again!

I returned to this problem. At this point it is not clear why my structuralFeature (TaskListener) object have upperBound value equal to "1" while in ecore model it equals to "-2". My model.ecore looks like:
index.php/fa/27518/0/

I'm getting it by calling next part of code:

TargetRuntime runtime = getTargetRuntime();
CustomTaskDescriptor customTaskDescriptor = runtime.getCustomTask(CUSTOM_TASK_ID);
List<TaskListener> taskLitenerList = ModelDecorator.getAllExtensionAttributeValues(eObject, TaskListener.class);
taskListenerList.getUpperBound(); // equals "1"

Probably because of this, as a result, I always get only one TaskListener element from extensionElements regardless of their actual number.
Is the return value of "1" a correct behavior?
Thanks.
