[news.eclipse.modeling.gmf] Re: Update existing diagrams after model cha

[Holger Kremss <Holger.Kremss@xxxxxxxxx>]

Hi Alex,

many thanks, this was a big help for me. The resource handler postLoad() 
was exactly what I was looking for. I'm now iterating through the 
notational model and search for missing (external label) nodes and 
create some:

while (it.hasNext()) {

  Node node = it.next();

  ...

  // Checking for type "5026" children

  ...

  Node n = node.createChild(NotationPackage.Literals.NODE);
  n.setType("5026");
  n.setLayoutConstraint(NotationFactory.eINSTANCE.createLocation());

  ...

}

I'm not sure, if this is 100% correct, but it does the job.

Regards,

Holger
