That's odd. I've just generated an editor from your .emf snippet and it works for me, with no compile errors at all.
I'd suggest that you remove all the generated code and try again, using the "Eugenia > Generate GMF editor" context menu entry from your .emf file. Sometimes, if you have been tweaking the .emf file again and again, the code generation process will not clean up some obsolete code and it will not compile. It's happened to me a few times.
thanks for your answer.
I already realized the issue you mentioned.
Because of that, i already create a complete new model from the .emf file. Generating all from the beginning everytime.
I even copy the code, created a complete new project, und rerun the generation.
But the issue is the same.
Any other suggestions ?
Can that be anything about versioning of GMF/EMF/Eclipse/Eugenia ?
