dOoMi, Where in the jbpm code is the StaleObjectStateException caught? Do you think my solution of using a process wide task as a lock would work? kukeltje, For us that are fairly new to jbpm and haven't followed the discussions in the past do you know where the discussion got to or be able to point us in the right direction regarding any resources? cheers View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4163506#...
