Hi,

I have the following problem in EWL:
I would like to know if a class has a certain stereotype.
Unfortunately my tries are not working like:
guard: (self.isKindOf(Class) and (self.getAppliedStereotype("x") <> null))

Please help!
Thanks
Regards,
attila

Hi Attila,

Assuming that you have defined the getAppliedStereotype() method (as
there's no such built-in method in Epsilon), the way to check whether it
has returned null is to use the isDefined() method: i.e.
self.getAppliedStereotype("x").isDefined()

Cheers,
Dimitris
