Ed,
I have read the bug thread and I am still not clear. It appears to me that the underlying work to enable OCL based generation is ready to be put into place, but that the actual generation code is still to be done. Do I have that right?
Is the patch from Bug 255469 going to be backed into EMF 2.5 or will it only be applied to 2.6?
We are now actively working on moving ORMF forward. We plan to move the high level analysis model (which is already in EMF) to a detailed EMF model starting around Christmas time, with an aim to be generating initial code from the model early in the new year. My preference would be define as much behaviour in the model as possible from the start using OCL. How practical is it a this stage?
Thanks,
Joel

Hi,
I was ready to start trying this, but on looking at Bugzilla 255469 still needs to be put into an EMF build and probably more important 291365 still has to be completed for OCL. Can you please confirm that until both of these are fixed and in builds that this functionality will not be ready for testing.
While I would really like to be able to give this a go, nor do I particularly want to fight Windmills 
Thanks,
Joel

Hi Ed,
Best thing would be to rebuild the release notes generator using EMF to make it dependable
So what does it mean that the "The EMF things are done"? Where can I find clues on how to add constraints to a model? I am not that fussed if I can actually generate code yet from those constraints, but it would be nice to know that I will able to in say the next three months. If this means digging into the code for hints, then can you provide a few pointers on where to start. (But I hope not, because at the moment I am busy reading CDO code;-)

working the last while.

Will do.

Joel,
The bugzillas to support this were committed by Kenn and are in a
build. It's only the OCL registration that's needed. Kenn was planning
to write some helpful information about it, but like so many of us, he's
stretched for time. I think the bugzillas themselves have a bit of
information to get started...

I emailed Kenn Hussey about this and here is his reply

I actually provided fairly detailed descriptions of the EMF enhancements on the New & Noteworthy page for Helios - see http://wiki.eclipse.org/EMF/New_and_Noteworthy/Helios
As it currently stands, EMF now supports the ability to "plug in" delegates for constraints/invariants, feature settings, and operation invocations. However, in order to use a particular engine (e.g. the OCL engine), delegates for that engine must be plugged in. As you've discovered, bugs are open to do this for OCL, and I attached preliminary patches at one point (which I've since updated in my development workspace) but as yet I have been unable to find the time/funding to complete the work. With any luck, that could happen in time for the next milestone...
