Diogo Saad [http://community.jboss.org/people/diogosaad] created the discussion "[SingleSessionCommandService] Could not commit session" To view the discussion, visit: http://community.jboss.org/message/623200#623200 -------------------------------------------------------------- Hi All, I'm new to jBPM and I've designed a process definition to be executed thru jBPM console but I'm getting the following excepion: (NioProcessor-4) 15:12:35,737 ERROR [SingleSessionCommandService] Could not commit session java.lang.IllegalArgumentException: IOException while storing workItem 5: sae.Assinante           at org.drools.persistence.info.WorkItemInfo.update(WorkItemInfo.java:123)           at org.drools.persistence.jpa.processinstance.JPAWorkItemManager.internalExecuteWorkItem(JPAWorkItemManager.java:44)           at org.jbpm.workflow.instance.node.WorkItemNodeInstance.internalTrigger(WorkItemNodeInstance.java:105)           at org.jbpm.workflow.instance.impl.NodeInstanceImpl.trigger(NodeInstanceImpl.java:122)           at org.jbpm.workflow.instance.impl.NodeInstanceImpl.triggerConnection(NodeInstanceImpl.java:185)           at org.jbpm.workflow.instance.node.SplitInstance.internalTrigger(SplitInstance.java:100)... sae.Assinante is a POJO which is part of my domain model which is populated according to User Form variables. I seems to me that's an exception related for persistence matters. I did NOT configure any persistence at all and was wondering if it's necessary to run it thru jbpm console. What am I missing? PS: Please find attached my process definition and the pojo.
