[jboss-user] [JBoss jBPM] - Finding task instances for pooled actors
Hi all,
I'm trying to get a list of tasks for a user based on the pooled actors of that task.
Searching at the docs, I have found in section "11.3.4. Pull model" the
suggestion to use TaskMgmtSession.findPooledTaskInstances method. Trying to do that I get
a empty list of tasks. My process is based on swinlanes that use expressions to assign
tasks. Bellow is one part of the processdefinition.xml:
| <process-definition
| xmlns="urn:jbpm.org:jpdl-3.1"
| name="inss">
| <swimlane name="beneficiario">
| <assignment expression="group(beneficiario)"
class="br.unb.cic.identity.assignment.INSSExpressionAssignmentHandler"></assignment>
| </swimlane>
| <swimlane name="medico">
| <assignment expression="group(medico)"
class="br.unb.cic.identity.assignment.INSSExpressionAssignmentHandler"></assignment>
| </swimlane>
| <swimlane name="administrativo">
| <assignment expression="group(administrativo)"
class="br.unb.cic.identity.assignment.INSSExpressionAssignmentHandler"></assignment>
| </swimlane>
| <start-state name="Requerimento de auxilio doenca">
| <task name="Requerimento de auxilio doenca"
swimlane="beneficiario">
| <controller>
| <variable name="nit" access="read,write,required"
mapped-name="NIT"></variable>
| <variable name="cpf" access="read,write,required"
mapped-name="CPF"></variable>
| <variable name="ultimoDia"
access="read,write,required" mapped-name="Ultimo dia
trabalhado"></variable>
| </controller>
| </task>
| <transition name="" to="Marcar
pericia"></transition>
| </start-state>
| <end-state name="end"></end-state>
|
The strange part is that debugging the system, everything seems to be fine. The task
instance is in the database and 2 of the 3 conditions of the query used to get the list of
tasks for pooled actors (TaskMgmtSession.findPooledTaskInstancesByActorId) are met, the
actorId of the taskInstance is null and the task instance is open. The problem is on the
condition that compares that pooledActor.actorId to the swimlaneActorId, bellow is the
query used in the TaskMgmtSession.findPooledTaskInstances(String actorId) method:
| select distinct ti from org.jbpm.taskmgmt.exe.PooledActor pooledActor
| join pooledActor.taskInstances ti where pooledActor.actorId = :swimlaneActorId and
ti.actorId is null and ti.isOpen = true
|
The values stored in the important tables are:
| users:
|
| id:1
| username:test
|
| id:2
| username:test2
|
| id:3
| username:test3
| -------------------------
| groups:
|
| id:1
| name:beneficiario
|
| id:2
| name:medico
|
| id:3
| name:administrativo
| ---------------------------
| membership:
|
| id:1
| user_id:1
| group_id:1
|
| id:2
| user_id:2
| group_id:2
|
| id:3
| user_id:3
| group_id:3
| ------------------------------
| swimlane:
|
| id:1
| name_:medico
| actoridexpression_: null
| pooledactorexpression_: null
|
| id:2
| name_:administrativo
| actoridexpression_: null
| pooledactorexpression_: null
|
| id:3
| name_:beneficiario
| actoridexpression_: null
| pooledactorexpression_: null
| ----------------------------------
| swimlaneinstance:
|
| id:2
| name_:administrativo
| actorid: null
| swimlane_:2
| taskmgmtinstance_:2
| ------------------------------
| pooledactor:
|
| id:1
| actorid_:administrativo
| swimlaneinstance_:2
|
I think that this is the relevant data about the stored values at the database. As you can
see the value of the field that is compared on the query (pooledActor.actorId) contains
the name of the group that is assigned to that task, but the value that the method
(TaskMgmtSession.findPooledTaskInstances(String actorId)) receive is the actorId of the
user, and not the name of the group and then the query result is empty...
Can anyone help? Any clues ?
Thanks,
Bruno.
