Accessing inherited tag values from applied stereotypes [message #1855786]

I cannot succeed in getting value given to tags that are inherited by the stereotype applied.

The SysML::Requirements::Trace stereotype inherits from the SysML::Blocks:DirectedRelationshipPorpertyPath abstract stereotype that has the tag "sourceContext" defined (among others).

However when I try to get the value of sourceContext from and applied "Trace" stereotype using the EMF getValue operation, I got the following error message:

org.eclipse.m2m.atl.emftvm.util.VMException: java.lang.IllegalArgumentException: sourceContext
at public abstract java.lang.Object org.eclipse.uml2.uml.Element.getValue(org.eclipse.uml2.uml.Stereotype,java.lang.String)

When I use the very same operation with "owned" tags (from other stereotypes) it works well.

Is there anyway to access inherited tags?

I've no experience with complex profiles that use stereotype inheritance, but I'll venture a guess: have you tried to access the value using the DirectRelationshipPropertyPath stereotype as a parameter instead?

In any case, ATL/EMFTVM is just passing the error message from the underlying UML metamodel implementation. If this does not work, it is probably best to ask again in the UML forum.

Cheers,
Dennis
