The whole deploy from the IDE process seems very brittle. I took the websale example, it worked and deployed fine, then I added a node to the diagram without any transitions to the existing process, and I get the same deployment error. Then I removed the node, and it still wouldn't deploy. Then I used local history to revert to the process from before I started monkeying with it, and it still won't deploy. Sometimes, deleting the gpd.xml and forcing it to regenerate seems to help, but only sometimes. What I wanted to do was to start with the example, make a small change, make sure it still works, and continue, but the smallest change, even after it's undone, breaks the deployment process.
