[news.eclipse.modeling.m2m] Re: [ATL] unspecified ATL error

Hello,

Can you please remember to use the [ATL] prefix?

This error is actually an EMF model loading error. We should look into 
wrapping this kind of error, in order to report them more clearly.

According to the error message, the DeploymentDiagramEditModel on line 5 
 is invalid. However, line 5 contains a ComponentEditModel.
It seems that there is a problem with the metamodel (e.g., that the 
model does not conform to the metamodel given to EMF).

I had a quick look at the .ecore files in meta.rar: it seems that you 
have several packages with the same nsURI.  This cannot work properly 
because nsURI is used as an ID. You should try to correct this problem 
in the metamodel files, and in the model.
