User development, A new message was posted in the thread "HistoryService": http://community.jboss.org/message/529888#529888 Author : Paolo F Profile : http://community.jboss.org/people/emp.tyres Message: -------------------------------------------------------------- Hullo,      anyone ever had issues with an application that works 100% OK, but when calling HistoryService queries only gets zero results?        This is probably not an issue in the "JIRA" sense, rather I am looking for something arcane I may be overlooking. I am using 4.3 on a mem: hsqldb db, wrapped the ProcessEngine into a signleton, and accessing it from an application being tested with plain Junit TestCases. Everything running smooth as expected, except for ProcessInstanceQueries and ActivityInstanceQueries consistently returning an empty list.        I tried turning autocommit to true (the only hint in that direction I coudl find) in the hibernate config file, to no avail.        Anyone that ever experienced a similar problem has any hints as to what I should be double-checking?   TIA -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529888#529888
