Hello. I was trying to use the GPD eclipse plugin to design a test process definition. In fact, i have first open an existent process file i've previously hand-written. After moving the nodes on the diagram, i've just saved the changes, and close the file. At this time, le GDP has generated two new files : ".gpd.BP3.xml" and "BP3.jpg", using the origin file name "BP3.xml" of the process definition. The last one seems to be a static image of my process diagram as saved. The first seems to be the graphics layout of the same diagram...
When i try to open again the process defintiion, an exception is thrown. I've tried to close the project, exit from eclipse and run it all again, but the exception persists ! The only way to get back to a working position, is deleting the ".gpd.BP3.xml", obviously losing the diagram, and doing it all again ! I copy the statck trace and the files content at the end of the message... Any idea ? Does somebody has the same problem ? The GPD plugin is the version that comes with the starters kit 3.1.1... Thanks for any help !
