Basically I move MPart to another window and back. Below are steps
MElementContainer< MUIElement > parent = aPart.getParent();
parent.getChildren().remove( aPart );
MTrimmedWindow outWindow = emodelService.createModelElement( MTrimmedWindow.class );
outWindow.getChildren().add( aPart );
MWindow windowMain = ....
windowMain.getWindows().add( outWindow );
getPartService().activate( aPart, true );
//and back
aPart.getParent().getChildren().remove( aPart );
windowMain.getChildren().remove( aWindow );
MPartStack stack = getSelectedType( area, MPartStack.class );
stack.getChildren().add( aPart );
ePartService.activate( aPart, true );
and I got NPE:

exception is on line WWidgetImpl.activationCallbacks.clear(); so it means that widget is disposed several times.
Do you have any idea what I am doing wrong or if there is BUG in efxclipse?
