JBoss development, A new message was posted in the thread "Perhaps a bug in createHistoryActivityInstanceQuery when process has a fork": http://community.jboss.org/message/529025#529025 Author : Maciej Swiderski Profile : http://community.jboss.org/people/swiderski.maciej Message: -------------------------------------------------------------- Hi,   I have encountered similar issue when working on showing history of process instances in console: http://community.jboss.org/thread/148498   In addition, execution id was different (process_instance_id.xxx) for task nodes as well. I think (as Ronald mentioned on the above discussion - is just not yet implemented) that there is a lack of one method in HistoryActvityInstanceQuery that will allow querying by processInstanceId instead of only execution or definition id.   Perhaps we could file an jira issue and vote for it?!   Cheers, Maciej -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529025#529025
