Fred DERNBACH [https://community.jboss.org/people/fdernb] created the discussion "Problem yith Human Task query" To view the discussion, visit: https://community.jboss.org/message/792549#792549 -------------------------------------------------------------- Hi, I'm setting up JBPM 5.4.0.Final over hibernate and Oracle. I'm using LocalTaskService, JPA 1 persistence unit over hibernate. It is working, a sample process can be started. But I'm struggling with a named query that does not return tasks while it should. To retrieve tasks, I'm now trying to call: public List<TaskSummary> getTasksAssignedAsPotentialOwnerByStatus(String userId, List<Status> status, String language) of LocalTaskService . That calls JPA named query *TasksAssignedAsPotentialOwnerByStatus* included in Taskorm.xml file. For parameter 'status' (a list is expected), I'm passing an ArrayList of size 1 with org.jbpm.task.Status.Ready enum value in it. JPA Query does not retrieve any task while it should. I've logged generated SQL and when run nativtely on database, it returns records as expected. However, the log file shows that the *binding of 'status' list parameter does not serialize correctly*. See log file below in *red*. The status list is binded in binary format ! Any idea what is wrong ? Fred *JPA query (extract of Taskorm.xml, see status binding variable in red):* </named-query>       <named-query name="TasksAssignedAsPotentialOwnerByStatus">           <query> select      new org.jbpm.task.query.TaskSummary(      t.id,      t.taskData.processInstanceId,      name.text,      subject.text,      description.text,      t.taskData.status,      t.priority,      t.taskData.skipable,      actualOwner,      createdBy,      t.taskData.createdOn,      t.taskData.activationTime,      t.taskData.expirationTime,      t.taskData.processId,      t.taskData.processSessionId) from     Task t     left join t.taskData.createdBy as createdBy     left join t.taskData.actualOwner as actualOwner     left join t.subjects as subject     left join t.descriptions as description     left join t.names as name,     OrganizationalEntity potentialOwners where     t.archived = 0 and     potentialOwners.id = :userId and     potentialOwners in elements ( t.peopleAssignments.potentialOwners  )  and     (     name.language = :language     or t.names.size = 0     ) and     (     subject.language = :language     or t.subjects.size = 0     ) and     (     description.language = :language     or t.descriptions.size = 0     ) and     t.taskData.status in (*:status*) and     t.taskData.expirationTime is null           </query> *Log file* *(see binding of status list variable in red)**:* DEBUG 11439685[RMICallHandler-20](Printer.java:106) -
