[news.eclipse.modeling.gmt.amw] Re: newbie Question: "WLinkEnd not exten

[Nick <nick@xxxxxxxxxxxx>]

I have tried to chase down where things go wrong by debugging the 
plugin. All appears well until the mw_core model is loaded and 
transformed into ecore. It throws the following exception which I hope 
will help to trace my problem. Running outside of a debug of the plug-in 
this exception is hidden - what I saw was the side-effect of it during 
later processing.

Regards

Nick
