[news.eclipse.modeling.gmf] LayoutService.layout() in LayoutEditPolicy

[Esteban DUGUEPEROUX <dugueperoux.esteban@xxxxxxx>]

Hi,

I have a gmf editor with a custom ILayoutNodeProvider, I can call my 
ILayoutNodeProvider with "Arrange All" GMF actionSet button, layout is 
correctly executed.

Now I want this ILayoutNodeProvider be executed each time a Top Node is 
 added to my Diagram.

Where can I insert my LayoutService.layout(...) call?
It seems in LayoutEditPolicy but this doesn't works.

Thanks.
