applyStereotype on input model elements [message #908348]

I use the eclipse QVTo and transform an uml model into an other uml model. The input model is also the output model (transformation t(inout umlin : UML) ...).

Question:
I can apply a stereotype on an element which i create before but i can not apply a stereotype on an element which is from the input model. That means an element that is not created during the transformations.

this works:
var c : Class:= object Class{name:="class"};
model.getClassDiagram().packagedElement+=c;
c.applyStereotype(c.getApplicableStereotype("myStereotype"));

but this not:
var c : Class:= model.getClass("myClass");
c.applyStereotype(c.getApplicableStereotype("myStereotype"));

the test c.getAppliedStereotype("myStereotype") <> null; is in both cases true but in the second case the output model file does not apply the stereotype on the element.

Hi

I'm afraid you're beyond my knowledge of the code. I'm gradually getting
to grips with stereotypes fro OCL and Papyrus; QVTo later.

However, as a result of a more general M2M discussion, I wondered how
output stereotypes could work at all in a declarative fashion.

After some investigation I spotted that the QVTo specification has a
"Type & Stereotype" syntax. I have no idea whether this is supported yet
in QVTo.
