Answer 1

I had the same issue, I fixed it following this solution.

You need to register your package before loading your model.

I added this line:

EPackage.Registry.INSTANCE.put(XXXXPackage.eNS_URI, XXXXPackage.eINSTANCE);

in the method registerPackages of the java class GeneratedHMTL.java which I use for code generation with XXXX as the name of your model

I hope this will help you.
