[jbpm-issues] [JBoss JIRA] Resolved: (JBPM-1075) org.hibernate.hql.ast.QuerySyntaxException in org.jbpm.db.TaskMgmtSession.findPooledTaskInstances(List actorIds)

org.hibernate.hql.ast.QuerySyntaxException in org.jbpm.db.TaskMgmtSession.findPooledTaskInstances(List actorIds) ---------------------------------------------------------------------------------------------------------------- Key: JBPM-1075 URL: https://jira.jboss.org/jira/browse/JBPM-1075 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM 3.1.4, jBPM 3.2.0, jBPM 3.2.1, jBPM 3.2.2 Environment: java version "1.5.0_04" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05) Java HotSpot(TM) Client VM (build 1.5.0_04-b05, mixed mode, sharing) Reporter: Jo Geraerts Attachments: patch I encountered this bug when I was developping an application with jboss seam. At some point there was a Actor with no group ids. The processInstanceList component will invoke the getGroupTaskList(List actorIds) with a List with 0 entries. So we end up in org.jbpm.db.TaskMgmtSession.findPooledTaskInstances(actorIds) with the same List ( with 0 entries) I get this Exception: 10:43:42,265 ERROR [TaskMgmtSession] org.hibernate.hql.ast.QuerySyntaxException: unexpected end of s ubtree [ select distinct ti from org.jbpm.taskmgmt.exe.PooledActor pooledActor join pooledActor.taskInstances ti where pooledActor.actorId in ( ) and ti.actorId is null and ti.isSuspended != true and ti.isOpen = true ]
