Hi, I have the following problem when trying to call qvto from Java.

I have a simulink2uml.qvto which transform simulink model into uml model. It works perfectly if i call it from the "Run configurations"/"Operational QVT Interpreter". All the uml stereotypes are well applied.

However, if I call the transfor from Java. There are always an error each time a stereotype is applied:
index.php/fa/21959/0/

Note that, the uml profiles (such as sysml) are well applied.
The below figure shows that the stereotypes are well applied in "Run config" mode:
index.php/fa/21960/0/

But it does not work when the transfor qvto is called from Java:
index.php/fa/21961/0/

All attributes of the applied stereotypes are missing.

Do you have any idea about this kind of problem?
Is there anyone encounter the same error?

Thanks for your help.

Hi

Maybe your transformation violates the Eclipse UML "business logic", which
allows to apply a stereotype to an element only if that element is properly
contained (e.g., a Class must be contained in a Package first in order to
apply a stereotype successfully).

The reason why it works from the Operational QVT Interpreter could be, that
the Run configuration is invoked on a dynamic instance of your UML model,
which does not enforce the above restrictions. Is that possible?

Kind regards
