Hi James
Thanks for your answer!
Fortunately the problem disappeared unexpectedly when I changed the =
Aggregation attribute of the memberEnd to "none". After switching back =
to 'composite' everything remained ok...

But after some experiences with the Genmodel there are some further =
questions:

- For every implementation class there is a getCacheAdapter() method =
generated (in the uml2.uml-impl-classes there is no such method) - this =
leads to a stack overflow using the generated editor plugin. Deleting =
the method manually resolves the problem. What am I doing wrong with the =
UML-Model/Genmodel?
- In the UML.merged.uml-model used as metamodel, what is the difference =
beween memberEnd Property with <eReference> Stereotype and the ones =
without Stereotype?
- Using an UML-model as metamodel is there a special behaviour in =
Genmodel when using ownedEnd's in associations (as in =
A_general_generalization)?

And finally a question which is maybe not just related with uml2:
Getting all the sources from CVS (emf: 200701110200 uml2: 200701111331) =
on 3.3M4 there are several errors in the UML2 projects even after =
updating the classpathes (org.eclipse.uml2, .uml2.importer.rose, . Is =
that just a strange behaviour of my environment?

Greets, Andreas

Hi Andreas,

I just tried this on my machine with a contrived example and it seemed =
to work fine ( If I understood this correctly ;) ).
Would it be possible for you to send more information or a snippet of =
your metamodel so I can inspect it.
What errors are you seeing in the impl class?

Regards,

- James.

Hi all
I'm trying to make a new language metamodel on the basis on UML.uml =
and using UML-Genmodel. In principle, the process is working but with =
the following aspect I get into trouble:

- In my metamodel I have two classes with an 1 -- 0..* association
- the creation of the genmodel works well
- after model-code generation, there are errors in the impl-class of =
the 0..* -side: in the following code-snipped the varable ownedrules is =
not declared in the class
- if I change the Multiplicity to 1, the resulting code works
public EList getOwnedrules() {

if (ownedrules =3D=3D null) {

ownedrules =3D new EObjectWithInverseResolvingEList(

MappingRule.class, this,

UMLTPackage.TRANSFORMATION_GROUP__OWNEDRULES,

UMLTPackage.MAPPING_RULE__TGROUP);

}

return ownedrules;

}

In the attachments there are some pictures of the .uml and .genmodel =
to get the context.

Anyone an idea
Regards, Andreas
