User development, A new message was posted in the thread "how to find all processInstance": http://community.jboss.org/message/528424#528424 Author : Maciej Swiderski Profile : http://community.jboss.org/people/swiderski.maciej Message: -------------------------------------------------------------- HI,   it seems like key is not set in JBPM4_EXECUTION table that's why the list is empty.   You could do one of two things: 1. use process definition id to return all process instances of given definition 2. assign process definition key and process instance key while starting, this could be a solution if you can use this pair when querying for process instance and then you could use processInstanceId, check out user guide http://docs.jboss.com/jbpm/v4/userguide/html_single/#withakey For instance, you could use something like this: DEMO.{file_name}   Cheers, Maciej -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/528424#528424
