Ok, i was able to build from source by creating a feature project and pulling in the source from Git.
When exporting the feature it built all of the plugins as well. I dropped this into eclipse and it looks to be working ok.
However, it seems that the diagrams i author with this editor, do not appear to be compatible with the guvnor web process authoring tool. I can't seem to load the file once i add it to guvnor.
Is that suppose to be the case or am i doing something wrong? The original jbpm editor works fine for the most part as documented.
Thanks
