jPDL designer loses changes and cannot edit file anymore
--------------------------------------------------------

                 Key: JBIDE-3618
                 URL: https://jira.jboss.org/jira/browse/JBIDE-3618
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: jbpm
    Affects Versions: LATER
         Environment: Windows xp 32-bit
            Reporter: Hedley Proctor


I've created a number of workflows using the Eclipse jPDL designer. Yesterday I created a fourth workflow by copying a previous one. After about an hours work, I had added another 10 states to the workflow. I saved it and shutdown Eclipse. Now I have opened Eclipse and none of the changes to the workflow have been saved. The Eclipse local history shows the last file version available as 17:22 yesterday, whereas in fact I worked until about 18:30.

Also, the file that remains is corrupt. It has transitions into and out of a state that doesn't exist. When I try to delete the transition in, in is deleted from the file, but it still remains on the graphical view. The Eclipse log shows a DOM parsing error:
