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.
