Hello,
I want to create automatically a child node 'Trigger' when I define a node 'task', so I customized my TaskCreateCommand as follows:
/**
* @generated NOT
*/
protected CommandResult doExecuteWithResult(IProgressMonitor monitor,
IAdaptable info) throws ExecutionException {
GioLike.Task newElement = GioLike.GioLikeFactory.eINSTANCE.createTask();
GioLike.FIMode childHolder = (GioLike.FIMode) getElementToEdit();
childHolder.getTasks().add(newElement);
//custom code:
GioLike.Trigger newTrigger = GioLike.GioLikeFactory.eINSTANCE.createTrigger();
newElement.setTrigger(newTrigger);
doConfigure(newElement, monitor, info);
((CreateElementRequest) getRequest()).setNewElement(newElement);
return CommandResult.newOKCommandResult(newElement);
}
In principle it seems to work , because it creates the trigger inside the Task. However, when I save the diagram the trigger is not saved, so when I close and open the diagram it has dissapeared.
Does anybody know what am I doing wrong?

Are you using GioLike as an EPackage name? Using upper case letters in
package names is a bad idea.

Is the Task.trigger a containment reference? This Trigger instance
will need to be contained somewhere if not here.

Hi both,
I still haven´t fixed the problem.
When I save the diagram file, triggers do appear in the diagram file, but they do not appear in the XML model file!! And if I close the diagram file and open it again, they have disapeared also in the diagram file. It is very strange, isn´t it?
I also tried the FeatureSeqInitializer as Ralph suggested, but it doesn´t work either. Does what I did:
- Node Mapping <Task/Task>
---- Feature Seq Initializer <Task(trigger)>
------- Reference New Element Spec <trigger:=new Trigger[1]>
---------- Feature Seq Initializer<new Trigger()>
The result in this second case is exactly the same as in the first one (modifying code by hand).
Can anybody help me?
