Hi all,

I've implemented EVL validation in my GMF application, I've difined my own rules in *.evl file in an external plugin (as I read in http://www.eclipse.org/gmt/epsilon/doc/articles/evl-gmf-inte gration/ ): it's working fine, but on my console i got the following:

java.lang.NullPointerException
at org.eclipse.epsilon.emc.emf.EmfUtil.getEStructuralFeature(Em fUtil.java:50)
at org.eclipse.epsilon.emc.emf.AbstractEmfModel.knowsAboutPrope rty(AbstractEmfModel.java:137)
[...]

and the rules implemented at EMF Model level are not respected; anyone knows about that problem?

Regards,
Giovanni.

Hi Giovanni,

The EVL/EMF integration has been implemented to respect existing EMF
validators. Could you possibly share a minimal configuration that
reproduces this problem so that I can have a closer look?

Cheers,
Dimitris
