Hi everyone!

I would like to load two models when launching the generation of a template. Is it possible?
Basically I've two UML diagrams that contain the information I need to properly generate a file.

Thanks in advance!

Hi,

Maybe I wasn't clear. The 2 two diagrams that I need share the same metamodel.

Hi,

If you want to use multiple models in your generator, you should start with one of the models and then navigate to elements of the second one in the generator. If the second one is not loaded, you can use the code in the comment in the method "doGenerate" (//org.eclipse.emf.ecore.util.EcoreUtil.resolveAll(model)).

Probably the information above is useful, but I'm just a beginner using acceleo.
If someone could provide me some help I would appreciate it very much.

Thanks.

Hi André,

What this basically means is that you do not "need" to load the two models if there are links between the two : the references will be loaded automatically as you navigate your models. For example if you have a two models "library.ecore" and "types.ecore"; library.ecore contains a class "Book", types.ecore contains a class "CirculatingItem". If the super-type of class "Book" is "CirculatingItem", then there is a "natural" link between your two models. You only need to load "library.ecore" and feed it to Acceleo : references will be automatically resolved when you try to access [book.eSuperTypes/] from Acceleo.

If you want to be absolutely sure that all your models are loaded when you generate, without relying on lazy loading, you can use the proposed code, calling "EcoreUtil.resolveAll(...)" before starting the generation.
