[news.eclipse.modeling.gmf] Problem with connection on editor reload

[Uwe Südbeck <uwe.suedbeck@xxxxxxxx>]

Hello, me again.

I have problems to refresh my connections when i try to reload my 
editor. As i mentioned in an earlier post i have some objects that 
reside within a compartment. This compartment is collapsable and for 
this i finally managed to manipulate the connections to point on the 
collapsed Parent-Component instead of the position where the (now 
invisible) component is.

But when i now try to reload the editor i get some strange behavior. If 
there had not been any collapse action the result is ok, but as soon as 
i try to manipulate the connections in the mentioned way the result is 
crap.
It seems that the manipulated connections are kept in the drawing and 
the all connections from the Model that have been manipulated are added 
again.

So for this i tried to decollapse all Compartments programatically to 
get back to the state the drawing was created. If i do this within the 
Editor everything works as expected, but if i try to do this in my 
overridden reload method it wont work. How can i do this ?

An other aaproach i would accept is to completely delete all existing 
Connections and rebuild them from scratch by the reload function. How 
could i achieve this?

public void reload() {

  if(this.getDiagramEditPart() instanceof SCERootEditPart){
    SCERootEditPart sceRoot =
	(SCERootEditPart) this.getDiagramEditPart();
    //this decollapses the Compartments
    sceRoot.collapseRecurse(false);
  }
  //this is a reset i need for Layout
  ((SCEDiagramUpdater)EditorContext.getDescriptor()
	.getDiagramUpdater()).initialize();
  reload(this.getRoot(), this.getRoot().getURI());
}
