Hello folks,
I have no idea where to post this topic, since there is a lot of subforums in Eclipse's forum. Sorry if I made the wrong decision.
I have a project in which I put EAnnotations in the elements of my Ecore model and I use a Java Emitter Template that I copied from this tutorial here.
By doing such thing, I can write my OCL constraints in the Ecore model instead of hard-coding, which is pretty convenient.
In Eclipse Galileo, the template stopped working and I had to follow this thread to fix it. The solution was to rename one of the files.
Now, in Eclipse Helios the template stopped working again.
When I try to generate the model code from the ecore genmodel, I get some files with no classes inside. 
What should I do?
[And, by the way, I have no idea how the template works, I'm just a user of it.]
Thanks.

Hi Bob
This is a pretty appropriate newsgroup.
You have identified another reason why the earlier OCL Validation
attempts were so unsatisfactory; they rely on custom JET templates that
have a very fragile interaction with the master templates.
Helios introduced a much better way to do this, and it works on
Dynamic/Reflective models as well as genmodeled models.
If you use the OCLinEcore Xtext editor in Helios you can edit OCL
constraints within a textual view of your Ecore model. This gives you
syntax checking and hides all the EAnnotation noise.
The Indigo release adds semantic OCL checking and more Xtext goodies.
See the OCLinEcore tutorial in the Helios OCL Help.

Ed Willink
