[uml2-dev] losing all relationship when converting uml2 model to ecore m

[zzz good <zzzisgood@xxxxxxxxx>]

Hi there, 

I came across this problem when I tried to convert a simple UML class diagram to ecore model, all the relationship get lost in the generated ecore model, only classes and their attributes are reserved. I am using the latest eclipse 3.5 modeling EPP, Eclipse Modeling Tools, Build id: 20090619-0625 , which has UML2  tool 0.9, 
This is what I did: 
create a UML2 class diagram, add package, classes, attribute and association to it, choose the package in the UML editor, select "UML Editor" > Convert to > Ecore model, it generated a ecore model, open it with ecore editor, all classes and attributes are there, but no association.

Did I miss anything? Can someone help please?

Cheers,
Derek
