[Acceleo]Using 2 metamodels in combination with 2 separate model instances [message #932663]

Hello,

Context:
MM 1: ER metamodel
MM 2: Policy metamodel wich refers to metamodel1 and uses metaconcepts that are defined in MM1

Model1 (model1.er): instantiation of MM 1 which is created using an EMF generated editor
Model 2 (model2.policy): instantiation of MM2 which contains a reference to Model 1 and uses concepts defined in model 1

Problem:
I can define an mtl generation file using Acceleo which contains no syntax errors. However when I run this file there seems to be something wrong when I want to use the references in model2 to elements in model1. Seems like model2 cannot find model1.

Thanks in advance,
Frederik

Hi,

It seems odd, well you can force the loading of all the related resources by using the commented line (//org.eclipse.emf.ecore.util.EcoreUtil.resolveAll(model)) in the method "doGenerate" of your java launcher. You can look in the resource set of your model to check that both models are properly loaded (model.eResource().getResourceSet().getResources()).

Regards,
