Hi,
I have been trying to change a swimlane dynamically and when i'm done, i'm
saving both the task instance to which to swimlane would be attached, as well
as the process instance.
But i keep getting the following error:
ERROR [TaskMgmtSession] org.hibernate.TransientObjectException: object
references an unsaved transient instance - save the transient instance before
flushing: org.jbpm.taskmgmt.exe.SwimlaneInstance
I can't figure out what's missing, because when i print out the taskInstance's
actorId, I get the right value..
here is the error i get:

Here is part of my process definition:
<task-node name="task3">
|
| <task>
| <event type="task-create">
| <action class="org.jbpm.mennen.CommandeAction2"/> </event>
| <controller>
| <variable name="Date_demande" access="read"/>
| <variable name="transition" access="read"/>
| </controller>
|
| </task>
| <transition name="" to="task4"></transition>
| </task-node>
Here is my action CommandeAction2:
ProcessInstance pi = executionContext.getProcessInstance();
|
|
| Swimlane swimlane =(Swimlane) executionContext.getVariable("swimlane2");
| SwimlaneInstance swimlaneInstance = new SwimlaneInstance(swimlane);
|
| executionContext.getTaskInstance().setSwimlaneInstance(swimlaneInstance);
| executionContext.getTaskInstance().getSwimlaneInstance().setActorId("luc");
| executionContext.getJbpmContext().save( executionContext.getTaskInstance());
| executionContext.getJbpmContext().save(pi);
