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

[Holger Kremss <Holger.Kremss@xxxxxxxxx>]

Doesn't anyone else have an idea how to display the new external labels, 
when opening the old model diagrams? :-( I expect no complete code 
example how to do it, just some hints, which bring me back on the road. 
Is it really that complicated?

Any help is appreciated.

Thanks, Holger
