[news.eclipse.modeling.mdt.uml2] Re: Strategy for loading commercial UML

["Kenn Hussey" <Kenn.Hussey@xxxxxxxxxxxxxxx>]

Dawid,

I have successfully loaded XMI files produced by MagicDraw on several 
occasions in the past, so I suspect this is more an issue with the 
particular file/model than MagicDraw's serialization in general. FWIW, I've 
heard they're working on a version of their tool that's based directly on 
Eclipse UML2, so this shouldn't be an issue on the long term (but of course, 
I realize that doesn't help you with your current problem).

We'll take a look at your sample model and try to determine what's going on.
