Hi,

I use Luna M6. When I set use dynamic templates to true I get the following exception during model code generation:

java.lang.ClassNotFoundException: org.eclipse.emf.codegen.ecore.templates.model.PackageClass_

I did not put anything in the template directory so it cannot be caused by my templates. How can I find what is going wrong?

Hi,

the Problem could be solved by deleting the project and cloning it again from my code repository. Deleting and recrating the genmodel did not help. Deleting the workspace without the project did not help too.
