Invalid Type Literal error when using AQL Expression [message #1844677] Tue, 21 September 2021 09:06 Go to next message

Hello,

when I use an aql expression with "model::myType" I receive the error
Invalid Type Literal model::myType


For example in the aql expression
aql:self.eContainer().->filter(model::myType)


I found the following forum post where the same error occurs:
https://www.eclipse.org/forums/index.php/t/1090273/

They state that it could have something to do with model schizophrenia but in my odesign file I only reference one metamodel.

Could it be that I referenced the metamodel somewhere else that I am not aware of or is the error caused by something else?

Thanks in advance,
André

Hello André,
Your expression seems strange. "filter" is for a collection but eContainer() returns an EObject.
Maybe you want something like :
aql:self.eContainer().oclAsType(model::myType))

Regards,
Laurent

Hello Laurent,

Thank you for your answer.

It seems like that I did not correctly check my example for mistakes. I think I did not copy everything from my aql expression.

Nonetheless, even with your expression I still get the error "Invalid type literal model::myType".

So, if you know where this error origins from I would be really grateful.

Maybe, the "model" package is not known in the environment where the AQL expression is interpreted?
It is difficult to help more without more details. What is your environment; A runtime, a deployed product, ...?

If you use the "Interpreter" view, what is the result type of expression "aql:self.eContainer()"? The type is displayed in the "title area" just after the combo to select "Sirius interpreter": index.php/fa/41016/0/

The environment where the error occurs is Sirius Web.
There is probably no file where I can test it via the Sirius Interpreter in the way you mentioned?

How would I implement the "model" package within Sirius Web? I already have a dependency to the project.
