Hi,
I want to be sure. Are you talking about to build a web application with
our "old" RCP existing code ?
In that case RAP is a very exciting project :)
Thx,
Nicolas

Hello Dan,
in the current contribution there are no viewers yet. But for RAP we
need a component analogous to JFace which will provide the viewers. One
approach could be to implement this based on the w4t-viewers library,
but there is no final decision made yet.
Actually, we did some investigation using EMF inside RAP-Applications
(Yoxos on demand - http://ondemand.yoxos.com - uses an EMF-Model for
example). As the workbench part of RAP does not yet exist, there is too
much infrastructure missing to generate EMF-Editors.
Of course a webapplication adds a level of complexity due to its
multi-user nature. Therefore a RAP-based EMF-editor would be different
than its RCP counterpart. But apart from that, the transactional
behaviour of those EMF models would need to be solved at the model level.
