Hi everyone.
I have tried using GMF a number of times but never managed to do so. The
most problematic aspect I found was that the model transformation are in
only one direction, so when I had my model wrong things just could not
evolve... And also the code generated by GMF was simply unreadable.
But still, GMF has very nice graphic properties that are missing from GEF
and I was wondering if there is ANY way to work with GMF like it is done
in GEF (only programming with no models/transformations/etc - except
obviously for the EMF model which is a must).
Thanks

Vainolo

Please open bug reports and, if you can, provide contributions to
GMF-Tooling to make it better.

GMF = GEF + EMF. GMF requires an EMF model, and is efficient to deal
with EMF model. It is a mature API that you can obviously use to write
your own editor code.
Then, just do it ;)

Before I start reporting bugs I would like to learn more about the
framework but sadly have found little documentation. Can you give me any
pointers?

It is not only GEF+EMF. There seems to be a lot of extra complexity doing
the connections that has been really hard for me to understand. Again,
any pointers? The tutorials in the web are a bit outdated...
Thanks

Without details, I can't help you, but there is probably something
helpful in the wiki.
