Re: [uml2-dev] losing all relationship when converting uml2 model to ec

[zzz good <zzzisgood@xxxxxxxxx>]

Thanks James, 
This is confusing to me though? Then how do we construct ecore model from
UML? There is a UML importer besides annotated java, xsd, even rose
class diagram. how does it generates  EReference then?  It seems to be conceptually natural to convert association to EReference.

Cheers,
Derek

Hi Derek,

Ecore does not support associations as in UML.   The behavior you are describing is not a bug, it's simply how Ecore works.

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

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,
