    jbpm 5.3 - groups

      Hello,

      I've noticed in 3 different computer systems (centos, win xp, win vista) that when creating a process with a human task that only has a groupId specified (i.e. image.png), the following exception is thrown when reaching the point of the human task.

      By checking out the code of org.jbpm.task.service.TaskServiceSession at line 1011 a named query is called as follows,

      Query query = tpm.createQuery("TasksAssignedAsPotentialOwnerByStatusByGroup")
                                               .setParameter("userId", userId)
                                               .setParameter("groupIds", groupIds)
                                               .setParameter("language", language)
                                               .setParameter("status", status);
      

      However as seen in Taskorm.xml inside jbpm-human-task-core-5.3.0.Final.jar/META-INF, indeed the named query has no userId parameter

       

      <named-query name="TasksAssignedAsPotentialOwnerByStatusByGroup">
                <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,
           t.taskData.actualOwner,
           t.taskData.createdBy,
           t.taskData.createdOn,
           t.taskData.activationTime,
           t.taskData.expirationTime,
           t.taskData.processId,
           t.taskData.processSessionId)
      from
          Task t 
          left join t.taskData.createdBy 
          left join t.taskData.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 = :groupId 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>
                <!-- hint name="org.hibernate.timeout" value="200"/ -->
            </named-query>
      

      Is this the case or am i missing something??

      Thanks
