Hello,


I need to edit some features of some model objects via plugin eclipse.

My method to set "devicename" property of "SystemMode" object is defined like below :
	public void setDevicenameofSystem(){
		System.out.println(s.getSemanticResources().iterator().next());
		
		XMIResourceImpl xmiressourceImpl = (XMIResourceImpl) s.getSemanticResources().iterator().next();
		final SystemModeImpl var = (SystemModeImpl) xmiressourceImpl.getContents().get(0);
		System.out.println(var.toString());
		
		final ModelAccessor ma = s.getModelAccessor();
		System.out.println("can edit device name : " +ma.getPermissionAuthority().canEditFeature(var, "devicename"));
		
		try {
	    TransactionalEditingDomain ted = s.getTransactionalEditingDomain();
		CommandStack stack = ted.getCommandStack();
		System.out.println(ted.getResourceSet());
		RecordingCommand cmd = new RecordingCommand(ted) {

			@Override
			protected void doExecute() {
			var.setDevicename("Test");
				
			}
		};
		
		stack.execute(cmd);
		}
		catch (ServiceException e) {
			e.printStackTrace();
		}	

		
}


I get as results :
ExternalJavaActionModelAnalysis
Work Session :Local Session: representations.aird
org.eclipse.emf.ecore.xmi.impl.XMIResourceImpl@10412e2 uri='platform:/resource/Demo/My.modemodeling'
modemodeling.impl.SystemModeImpl@f508fb (devicename: SystemMode)
can edit device name : true


!ENTRY org.eclipse.equinox.registry 4 1 2015-06-08 12:32:51.363
!MESSAGE Plug-in "xxx.modelanalysis" was unable to instantiate class "xxx.modelanalysis.ExternalJavaActionModelAnalysis".

	at org.eclipse.emf.transaction.impl.TransactionalEditingDomainImpl.activate(TransactionalEditingDomainImpl.java:508)
	at org.eclipse.emf.transaction.impl.TransactionImpl.start(TransactionImpl.java:204)
....


I read documentation about "TransactionalEditingDomain", "Session", "ModelAccessor" and "PermissionAuthority" but I don't find a clear example for my requirement.

Thank you.

Hello,

Executing a recording command using the command stack of the
Transactional Editing domain is the proper way.
How do you call this method? As there is no parameter I guess this is
not a Java Service[1], called from a Sirius Tool operation[2]. Maybe it
would work better this way.

Regards,
Steve

I forgot to add, if you use this code in a Java Service, executed from a
tool with a set operation, you should have the context (change context
operation) on your SystemMode element. In your java service, you should
have a SystemMode as first parameter (public void
setDevicenameofSystem(SystemMode systemMode){). Then in your expression
you can directly call it [setDevicenameofSystem()/] as the first
parameter will use the current context.

Regards,
Steve

Hello,

Thank you. I resolved the problem to edit model elements via java method.

In the first time, I call my method via Viewpoint Specification with an External Java Action in a Double Click to edit element. My Java class is defined in plug in extension point "org.eclipse.sirius.externalJavaAction". I use Session service to get TransactionalEditingDomain. But in my test i get an error message "Cannot activate read/write transaction in read-only transaction context".


In the second time, I call my method via Viewpoint Specification with a Java Services following your steps detailed in your last message. And I use the same implementation with Session service and TransactionalEditingDomain and finally i can edit the element of the model via my method.


Thank you.
Yassine.

Hello,

I am glad you resolved the problem.

Ok you were using an External Java Action. I am surprised of the
read/write transaction exception. However, the External Java Action is
already executed in a transaction so in that case you did not need a
RecordingCommand executed on the command stack. This embedded execution
probably caused this issue, but this should be reproduced on our side to
verify.

Regards,
Steve
