Hi, Mark,
What, specifically, is going wrong? Do you see incorrect code being
generated from your custom templates (note that there have been numerous
changes in the base EMF templates since this article was written). Are you
getting OCL parsing problems? Exceptions? Any messages in the log? What
does debugging show?
Note that the example illustrated in that article has not and will never be
incorporated into OCL and/or EMF in the form in which you see it (is that
what you were expecting?) There is work under way to provide hooks in the
implementations of EStructuralFeatures and EOperations that OCL could
eventually plug in to.
Cheers,
Christian

Hi Christian,
I was expecting the form as illustrated in the example. I thought that you
could add OCL directly to the ecore model as shown (using something like a
right click on a model element and adding OCL). So if you have an Ecore
model where do you add constraints?
Thanks for your help,
Mark

Hi, Mark,
Do you mean, that the Ecore Editor no longer allows you to add EAnnotations?
You can, certainly, add these OCL annotations to an Ecore model, but neither
EMF nor OCL will know what to do with them.
The code-generation extensions illustrated in the article are not packaged
in the EMF SDK nor the OCL SDK. They are an example that you implement
yourself, following the article, using EMF's dynamic templates support.
The article does link to a downloadable ZIP of the example projects; these
work with EMF 2.3 and OCL 1.1; I have not verified that they still work
with EMF 2.4 and OCL 1.2, but I don't see why they wouldn't.
Cheers,
Christian
