Just to add a argument to merge in the forms.xml: If the process-definition.xml is saved for any ProcessDefinition (I remember, there were plans for that?), a gui framework can easyly load the XML with the form mappings from the process definition of the right version for every running process. That would be a good step towards supporting really different process versions. Mixing in the forms sound really horrible for me. Okay, I am not the Web-Gui-Fan, but even then, some seperation of concern should be kept! Hope, it was a good party Ronald?
