Hi all!

I need to create an ATL trasformation that, starting from a weaving model and two generic model, allows to generate a new weaving model.

My interested is related to the instances of the two input model.

In the weaving model i have information about the metaclass relation, and i want to generate all'instance starting from this relation, not knowing the metamodels of the input models.

I've founded this function, getReferredElement, that seems to be right for me, but when i call it i receive an oclundefined element.

Starting from this result, i can call allInstancesFrom('left or right model') n order to obtain the instances.

Where i'm wronging?

Thanks

Maybe i've an answer.

If you wanna generate all instances of a model m which is conforms to a metamodel mm (mm is conforms to Ecore) not knowing the metamodel at 'compile time', you can use this strategy:

(create .. from .. ART : ARTMM) -- ART is artifact
s.debug(MOF!EClass.allInstancesFrom('ARTMM')->collect(i | i.allInstancesFrom('ART')));

Naturally we can play with the desidered MOF type (in this case EClass) in order to be more generic

I hope this is right!
