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. https://community.jboss.org/servlet/JiveServlet/showImage/2-738279-18646/image.png https://community.jboss.org/servlet/JiveServlet/downloadImage/2-738279-18646/310-139/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
