Hi Miguel,
yes, thanks a lot for clarifying this. We are open to any new technology of
course for new components or projects. If you have a survey or came to some
conclusions concerning these technologies it would be nice if you could
share them with us.
We were always planning to implement the workflow editor with GMF somewhen
again (since the EMF metamodel and all the figures already exist), simply in
order to see what's easier and where the problems are, but didn't find the
resources to do so. So any experiences here are interesting for us, too!
Best regards,
Florian

Betreff: RE: [jwt-dev] JWT and GMF
Hi Marc, others,
I would like just to clarify my/team position: GEF is the technology we have
been paying so far so I'm not against GMF (basically because we never played
before with it).
So, what we have experimented is that GEF is something hard to learn so we
decided to also have a look to GMF (seems to be easy to start but hard to
customize) to have a better overview of this technology and so be able to
compare both with one target in mind: what is the best Eclipse technology to
build a BPM graphical editor?
In this context Rodrigue is doing some experimentation with GMF which I
think is a good complement with the work that Pierre and Marc are doing
around GEF.
BTW, Pierre is about to post on the last developments around JWT.
Best regards,
Miguel

Hi Rodrigue
GMF has been discussed already but maybe not openly (on the mailing list
etc.). It helps configure and generate a diagram and its palette. Its good
point is that it extends EMF's modeling and generation chain up to the
diagram UI. It's bad point is that UI is a field where you may want to
tinker to get exactly what you have in mind and that the configure /
generation paradigm rather gets in the way. So if your default generated
diagram is OK with you (and you've succeeded in generating it !), you've won
some time and an architecture, otherwise...
Basically, right now the existing JWT code is GEF, nobody has the resources
to rewrite it, and the main JWT architects (Florian, Miguel, me and I
suppose Pierre) dislike GMF's generation magic. I've tried a little bit GMF
and closely followed Stéphane Drapeau who at SCA Tools has successfully used
it, and it seems to me that it has a steep learning curve, can really make
tinkering difficult (for example, Stéphane wanted to have concept icons on
top of the border of another) and would be harder to customize to support
model and view extensibility. These two last points come from the fact that
like EMF, it is aimed at creating end-user tools rather than extensible
tools that other vendors would build on.
But it really comes down to the fact that our view developers are Augsburg's
and are experts on GMF and not EMF, and that Miguel I guess also prefers GEF
right now. I personally think that making views-like things in GMF would be
way harder than in GEF and require heavy knowledge of GMF, even possibly
help it evolve.

Marc
