[JBoss Eclipse IDE (users)] - <start-page> doesn't display in designer
by rohanmars
Hi
I get the following error when I use the jBPM designer to view a <start-page> page flow. I've tested with the latest 2.0 beta version. If I change the <start-page> to a <start-state> tag then it displays correctly. Has any body got the <start-page> flow to display correctly?
Thanks
Rohan

[JBoss Seam] - A little confused about remoting and conversations
by chris.morrisette
My intended usage of remoting is a single conversation for my entire page experience.
In the Seam documentation, it says:
anonymous wrote : If you are working with just a single conversation, then you don't need to do anything special. (regarding setting the conversation id). Therefore I currently don't attempt to ever set the conversation id.
In addition, in the onload event of the page, I begin the conversation by invoking a method on a SFSB with the annotation @Begin.
My problem is that conversation id changes occassionaly (not reliably reproducable), even though I am invoking the same SFSB.
Here is an example of the debug output where the conversation id changes:
| Sun Dec 17 2006 20:29:36 GMT-0500 (Eastern Standard Time): Request packet:
| <envelope><header><context><conversationId>57</conversationId></context></header><body><call component="serviceBusiness" method="getServiceParameters" id="17">
| <params><param><number>1</number></param></params><refs></refs></call></body></envelope>
|
|
| Sun Dec 17 2006 20:29:36 GMT-0500 (Eastern Standard Time): Response packet:
| <envelope><header><context><conversationId>2</conversationId></context></header><body><result id="17"><value><str>..somedata...</str></value><refs></refs></result></body></envelope>
I would prefer not to have to set the conversation id all over the place, if I can avoid it (although its not that big of a deal). More importantly, I would just like to determine if I am doing something wrong.
Thanks for any help you can offer.

[JBoss jBPM] - Finding task instances for pooled actors
by bnsbr
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.
