Listening to changes in the BPMN Diagram [message #652680]

Hi,

I am trying to integrate with the BPMN modeler. My domain model is also an EMF model.

I wanted to listen to changes in the BPMN EMF model and correspondingly make changes to my domain model.
I created my EContentAdapter to listen to these changes:

editor.getDiagram.getElement().eAdapters().add(myListener)

However whenever the name of an Activity (Task) is modified I dont get any notifications. I only get notifications on Add and Remove.

I am not sure why this is happening. What exactly am I missing?

Also I want to listen to changes on even those BPMN models (editor) that are already opened (from my previous run).
What would be the best way to achieve this.

Any help would be really appreciated.

Thanks a lot,
Nidhi

/**
* @see org.eclipse.gef.editparts.AbstractGraphicalEditPart#activate()
*/
@Override
public void activate()
{
add the following code in your root editpart so that all your models get registered for model changes and correspondingly call your refrshvisuals

if( !isActive() )
{
super.activate();
getTarget().eAdapters().add( this );
}
}

/**
* @see org.eclipse.gef.editparts.AbstractGraphicalEditPart#deactivate()
*/
@Override
public void deactivate()
{
if( isActive() )
{
super.deactivate();
getTarget().eAdapters().remove( this );
}
}
