Hibernate queries on jBPM DB tables

[lauradp]

Hello everybody,

I'm trying to make a query jBPM task table, but I always get an empty list even if I can see result by DB UI.

My mapping is:

<class name="MyTask" table="task" dynamic-insert="true" dynamic-update="true">

                    <subselect>

                              select id, priority, processId, processInstanceId, processSessionId, status, workItemId

                              from task

                    </subselect>

                    <id column="id" name="id" type="java.lang.Long" />

                    <property name="priority" column="priority" type="java.lang.Integer" />

                    <property name="processId" column="processId" type="java.lang.String" />

                    <property name="processInstanceId" column="processInstanceId" type="java.lang.Long" />

                    <property name="processSessionId" column="processSessionId" type="java.lang.Integer" />

                    <property name="status" column="status" type="java.util.String" />

                    <property name="workItemId" column="workItemId" type="java.lang.Long" />

          </class>

the query is:

session.createCriteria(MyTask.class).add(Restrictions.eq("processInstanceId", new Long(pid))).list();

Am I missing somethin??

thanks
