Hi, all,

Eclipse.org has published an article contributed by an EMFT committer,
entitled "Implementing Model Integrity in EMF with EMFT OCL". You can find
it here:

http://www.eclipse.org/articles/Article-EMF-Codegen-with-OCL /article.html

This article demonstrates a generative approach to model integrity using
EMFT OCL by implementing constraints and derived features directly in the
model, which differs from the EMFT Validation/Transaction approach of
third-party contributions of validation rules and triggers. The article is
written in a tutorial style, with a complete and fully functional example
available to dowload.

Cheers,

Christian

Nevermind,

I solved the problem by deleting the .JETEmitters-project and regenerating.
