Problems with 'generateModelRef()' from output model. [message #897612]

Hi Marco and all.
I'm trying to get the path to the output model by using the
generateModelRef() helper from the former AMW model handler in a
transformation where input and output models correspond to the same
metamodel.

Within an entrypoint rule, I have no problems using it for the input
model (Operations!OperationFlow.generateModelRef('IN') works ok), but
running it on the output model
((Operations!OperationFlow.generateModelRef('OUT')) throws a NPE.

My guess is that the cause is being within an entrypoint rule, and that
the output elements are not yet generated. I need, though, this info in
that precise moment. Any tips on this one?

Best regards, and thanks again for all your help,
Juan Pedro

Hello,

yes, this is the problem. The output elements does not exist yet, so they do not have an ID.

We had a similar issue with the traceability use case. As a solution, we used an endpoint rule to set up all the IDs.
