Building RCP Application with GEF Editor [message #223547]

Hi, I am trying to build a simple RCP application that will contain a GEF
editor in it. I am not quite sure how to go about adding the GEF editor I
made (followed the shapes example) into the RCP workbench in the default
RCP Application with a View template. Or if using the blank "Hello World"
RCP App template would be easier let me know and what I have to do to make
this editor appear.

I'm currently trying to do the same thing. I've found the following
reference: http://www.eclipse.org/articles/Article-GEF-EMF/gef-emf.html -
see the section titled "Bonus: Shapes Example goes RCP!". I'm still looking
at it, but I'm hopeful it's a good start

I used that tutorial to figure out how to add the editor in, but it
explodes every time I try to open an editor. The sample does not load
the editor either. I tried uninstalling and reinstalling eclipse
entirely and cleaning out the .meta files and folders from my workspace.
I even tried to rewrite the code by following the example here
http://www.eclipsecon.org/2006/Sub.do?id=71 just to get a very simple
stripped down GEF editor and this blows up too. The stack trace on this
newer explosion is below. What am I missing here?

Alright, solved that problem. But now I get the generic error "An error
has occurred when activating this view" . That error shows up whether I
have the Palette initialized or not. So I am sure that it has something
to do with my Editor which extends EditorPart.

Ok, I actually figured out all my problems and have a working (very
simple GEF editor in an RCP Application). I was thinking that sometime
in the near future I will document the code and post a walkthrough of
what I did to help people who are struggling to understand GEF or just
simply how to get it to open in an RCP context.

Dan,

I similarly had problems with my "simple" GEF RCP editor. Never got it
working. Did you get around to writing up a walkthrough? Or can you post the
source? Would be much appreciated!
