invalid type literal exception in aql expression [message #1852978]

Hey everyone,
I have currently problems with referencing Eclasses of the model in an aql expression.

An error has occurred with the expression 'aql:self.nodes.ocllsTypeOf(autoDesigner1::Node)': invalid type literal autoDesigner1::Node

However I have added the metamodel, which is located in the same workspace correctly and I can also refer to the classes in the "Domain Class" sections normally.

This Forum post references the problem too:
https://www.eclipse.org/forums/index.php/m/1852958/#msg_1852958
but I could not find any solution.
Can someone help me please?

I think that I should install/register the model into the eclipse instance, where the validation runs . However I dont know how I can do that without creating a new eclipse application

Hi AMir,

I'm not sure I understand the context: are you trying to write an aql expression in your VSM ? If so, did you add your metamodel to the Diagram (or other) Description ? In the Properties view, "Metamodels" tab.

Regards,
Glenn

Yes I have already added the metamodel. It is also loaded and I can access the Eclasses in the "domain class" sections for example (in odesign)
