[ATL] how to register multiple metamodel with Generic engine [message #537945]

Hello,
My input model conforms to a metamodel that rely on 2 other ecore metamodels.

When I register the metamodel in the Generic VM, I get a message when laoding the model that declares instances comming from depend metamodels.

I do not know how to register the other metamodels, the only solution I found was to merge all metamodels into one but this is not satisfactory.

Does anyone has any idea ?

thanks.

ATL "sums" up all needed metamodel.
So if you use your meta-model A as input meta-model of the transformation and A references a meta-model B, then you can use the EClasses of B in your transformation directly.

Nop, it is not a matter of transformation, it is a matter of xmi emf loading that fails to load the model that defines B metamodel instance.
I had the same problem with EMF transformation engine but I managed to register the B metamodel somehow and it workded, but I did not manage to do so with Generic VM???
