[ https://jira.jboss.org/jira/browse/JBPM-1082?page=com.atlassian.jira.plug... ] Tom Baeyens commented on JBPM-1082: ----------------------------------- bernd, do i understand this issue correctly ? in order for you to do simulation, you need to query the diff between 2 timestamp properties in the jbpm DB. and you didn't find an HQL way of getting that information. first, i do acknowledge that this is a normal feature request. it would be a normal next enhancement of jBPM 3. but the strategy in jbpm 3 for such queries has always been that users are on their own for such matters. so i don't see a problem if users have to go for native queries like you indicated. in jbpm 4 i would like to extend the core engine functionality to include portable querying of this kind of information. did the native queries solve the problem for you ? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
