Broken datamodel when a detached ProcInst is saved -------------------------------------------------- Key: JBPM-1115 URL: http://jira.jboss.com/jira/browse/JBPM-1115 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2 Reporter: Britt Miner Assigned To: Tom Baeyens I've noticed (accidentally of course, -ahem-) that if you attempt to call jbpmContext.save(processInstance) on a pi that was loaded outside of the current session, Hibernate will save a new pi with a new Id--however it will reference the same rootToken, etc. as the original pi, and all kinds of unexpected behavior quietly ensues. Of course, loading a fresh copy of the pi immediately before you do anything with it avoids the problem; however, a lot of serious data integrity hangs on remembering to do that every time. (for instance, when a pi being viewed in a UI is injected into an action component, the programmer must remember to load up a fresh copy before working on it.) Since failing to re-load a detached pi can result in what seems to be a broken jBPM data model, jBPM should probably be doing something itself to avoid the problem. I think there are possibly two ways to prevent this from happening: 1) Simply changing the HibernateSaveOperation.save(processInstance) method to saveOrUpdate() seems to perform cleanly. 2) Do a check on the pi, and throw an error if it doesn't belong to the current hibernate session. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
