[jboss-user] [JBoss jBPM] - possible schema changes needed to support deleteProcessInsta

[X490812]

Howdy - on my last post, I mentioned that deleteProcessInstance failed on fk constraints. I receved no response. My recourse was to go in and figure out all the entity bean mappings and fix them. I had to get the job done so I approached our dba. He suggested we modify the JBPM constraint tree so that when deleting from jbpm_processinstance, it would cascade to all associated runtime tables.  He did so. I tried deleting 77 process instances and it seemed to work fine - all runtime tables with associated data were deleted also - even parent / child relationships. I would like some jbpm schema guru to take a look at the changes and validate that we are not missing anything. Note - there are a few JBPM jira issues related to this problem (e.g., JBPM-785)
