Koen - something we can at least guard against in GA ? 

i.e. have the editor warn the user about the error ?

> 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:
