AQL oclIsKindOf not working [message #1793572]

Hi all,

I'm trying to check if a class is a subclass of another type for style customization.
I use the expression:

aql:self.oclIsKindOf(ns::SuperType)

But this doesn't work.
If I change it to Acceleo syntax it works:

[ self.oclIsKindOf(ns::SuperType) /]

What am I doing wrong?

Hi Ewoud,

In the .odesign file, did you add the metamodel in the tab metamodel of the representation?

Hi Julian,

Yes, the metamodel is added to the .odesign
All other aql queries work, except when I use oclIsTypeOf().
This is also the case when using the interpreter (changing self to self.target). It shows that the return type is a Boolean, but always returns false. Using Acceleo's square bracket syntax works, but adds additional dependencies to my project.

Am I missing a specific dependency? Other than default available when using EMF + Sirius specifier?

Maybe you haven't declare the required metamodels (those that declare the types used by the modeling tool).

Just open the MANIFEST.MF file of your project and add the plug-in that defines the metamodels (here: org.eclipse.sirius.sample.basicfamily) in the list of the Required Plug-ins (in the Dependencies tab).
