Eclipse Community Forums - RDF feed Eclipse Community Forums DiagramComposite displaying a BPMN2 model
I'm trying to develop a DiagramComposite that allows the display a BPMN2 model. Now, I've dived deep in the code of the BPMN2 editor, and it cannot be used easily (as the part that transforms a BPMN2Diagram element into a graphiti Diagram object makes lots of assumptions about being in a BPMN2Editor).

Some refactoring should be done, obviously, but I don't have time to do it myself and even simply copying some code to get a result in a DiagramComposite is overwhelming (damn you, unchecked casts).

Has anyone coded such a diagram composite before ? Any idea how I could do this simply, and avoid duplicating thousand lines of code?

Thank you Smile]]>

Re: DiagramComposite displaying a BPMN2 model
The bulk of the BPMN2 Modeler was developed before graphiti introduced the concept of a IDiagramContainer (which makes it possible to implement a graphical viewer/composite) and this was one of the biggest issues migrating the editor from graphiti 0.9.2 to 0.10.0. Yes, the code needs to be refactored, but we also need to maintain compatibility for graphiti 0.9.2 and juno. We already have three separate code branches for each of the different versions of graphiti (although the helios version of the editor will remain at 0.2.5, as this is no longer being kept up-to-date because we simply don't have the time Sad ). This means there's going to be an even larger diversion of the juno and kepler code branches and it's going to become even more difficult to keep merging bug fixes.

Currently I'm the only one working on this project and there is still quite a bit of work for new features and bug fixes, so if you or anyone else out there has some spare cycles to donate to the cause, I'd be grateful Wink
