I think, they correct the ID's, because the ID's were generated from the database during the first INSERT and so not known in advance. So we really need these second updates for the many-to-one associations. But why is that missing in the JTA version? May some small implementation issue in jbpm 3.2. I will investigate further. And I have created a JIRAA-Issue for that: http://jira.jboss.com/jira/browse/JBPM-944 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4035668#...
