Hi, I'm trying to create a modelling tool with sirius but wen I try to create the nodes in the modelling tool i got the error below.
It seems like the tool are not recognising the relations present in the metamodel as feature.

I also attached the metamodel related to this project.
thank you!

Hello,

Can you copy or describe how you set your creation tool and its operation? You may have an operation Set where the reference used is "entities" but the context is not the correct one and therefore the reference is unknown.

Regards,
Steve

Hi Steve,
I tried again using containers instead of simple nodes and now it is working. I realised that it is necessary once my metamodel defined entities as a content of another class (SourceVersion).
Thank you for your attention.
