oclIsKindOf returning unexpected values [message #1833603]

Is there an AQL query for the interpreter that can do a getType of a selected model element? I am trying to build some validation rules but when I query a model element for it's type using oclIsKindOf() or oclIsTypeOf() I get false for everything that I check; stuff from my ecore model and stuff that is built into Sirius.

I have been following this documentation to try and figure out what is going on and why I can't get the expected returns that I want from those methods.
https://www.eclipse.org/acceleo/documentation/

I have inheritances in my ecore model which is why I am using oclIsKindOf() to check if it conforms to the expected supertype. my inheritance is defined as such:

index.php/fa/39096/0/

Is there a way to get the type of the elements that are created in my editor? Or at least some way I can check what the type of the element actually is? Or why I keep getting false? This is the command that I am using in the interpreter: aql:[ self.oclIsKindOf(wFP_V2::Data)/]

Hi

Metamodel schizophrenia is a common cause of oclIsKindOf and related impossible type failures. You may have inadvertently loaded the 'same' metamodel more than once and so types from one do not conform to the other.

In Sirius you should probably be using not-genmodelled models consistently so use Ecore.ecore.
