Hi,

recently i encountered an error, when i try to start a transformation i get the following message:

Transformation runner initiliaze
Failed to load model extent uri=platform:/resource/AADLv1/in/TransModelv1.aaxl
For input string: "aadlSpec[@name=TransModelv1]

i thougth that Xpath could be the problem. The source models are provided in an XMI representation, object references are made with xpath. But the references work just fine in other parts of the source model.
Perhaps the source MetaModel is the problem ? The MetaModel is specified in multiple ecore files, referencing each other. I created one generator model and deployed the model code as plugin.
In the Metamodel Explorer i get for each source ecore-file a single MetaModel.
Has anybody expereience with multiple Metamodels or encountered the same problem ?

thanks in advance

regards

PS: Sorry for double posting, please just ignore the other post

I identified the problem

the provided source models in XMI representation use the XPath reference construct. Obviously QVT cannot resolve the references properly.

Thus the source models have to use the EMF reference format
