[jboss-jira] [JBoss JIRA] Commented: (JBPM-962) SuperState.nodes Mapping causes serious problems

SuperState.nodes Mapping causes serious problems ------------------------------------------------ Key: JBPM-962 URL: http://jira.jboss.com/jira/browse/JBPM-962 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2 Reporter: Bernd Ruecker Assigned To: Tom Baeyens Fix For: jBPM 3.3 The SuperState Node mapping in the database has a problem. When parsing a process, everything is done fine. All Nodes at the root level are added to the nodes-association at the process-definition and the nodes in the super-state are added to the super-state nodes. But after persisting we have a problem: For every Node the processDefinition-association is set (by JpdlXmlReader.readNodes). So we have a id in every database column for PROCESSDEFINITION_. Because of the many-to-one mapping in ProcessDefinition: <list name="nodes" cascade="all"> <cache usage="nonstrict-read-write"/> <key column="PROCESSDEFINITION_" /> <list-index column="NODECOLLECTIONINDEX_" /> <one-to-many class="org.jbpm.graph.def.Node" /> </list> we now load ALL nodes in the nodes-List in ProcessDefinition (instead of only root nodes). To make things worse, because of the NODECOLLECTIONINDEX_ overlapping with SuperState-Nodes, we only get some of the nodes (I think it is somehow random which ones). Took some minutes to catch that ;-) One possible fix would be to NOT set the processDefinition for SuperState-Nodes (not my favorite) or maybe improve the mapping to reflect the situation (sorry, there my hibernate expertise ends).
