I have implemented an OutlineView, that has 2 TreeEditParts(TEP) for one EditPart in Editor(2 TEP for one Model) and i have a problem with this, because if I select one of these TEP it jumps to another.
I understand the reason of that, but i can't fix it. Can somebody help me?

My opinion for the reason is a selection process in GMF:
if I select first TEP than it's selects corresponding object in editor, and than this object sends back select notification event to outlineview to second editpart, therefore it jumps.

The DiagramEditor has a selection synchronizer. by default, it would
have the treeeditpart and the Diagramedit part added to the
synchronizer. It also allows, some customization. Have a look at it.
you can get it with getSelectionSynchronizer() in the editor.

Thanks for the reply,
I have already tried to customize SelectionSynchronizer(method convert), but unsuccessful.
Which ideas do you have to prevent this problem?

One idea, would be to disable the synchronizer first (Extend it, and
make sure it doesn't call super.selectionChanged(...). Than you would
whatever you deem necessary for your app.

Another idea, is to add your 2nd TEP to the synchronizer .addView() method.

I faced the same problem with outline view.
Solution I followed is ..
extend the SelectionSynchronizer and override the selectionChanged(SelectionChangedEvent event) method to do synchronization for all other editparts except my implementations.
