[JBoss jBPM] - JBPM Context variable lifecycle
by ngeadah
I use the Seam annotations to launch a JBPM process and outject to the BUSINESS_PROCESS context. Everything works great but I find that the outjected variable gets "removed" from JBPM at some indeterminate later time. For example, after the process has been launched (and is in a wait-state), the following code which retrieves the task instances for the current actor and tries to retrieve the variable initially outjected:
| List<TaskInstance> tasks = context.getTaskMgmtSession().findTaskInstances(actorId);
| for (TaskInstance task : tasks)
| {
| Object variable = task.getVariable("NAME USED TO OUTJECT");
|
returns "variable" correctly as long I this code runs shortly after the process is launched. After a little while, "variable" is null. I was able to dertmine that my variable starts off looking just fine in JBPM_VARIABLEINSTANCE, but after a while, the row representing this variable is updated WITHOUT a TOKEN_ or PROCESSINSTANCE_ (those two fields, along with a few others become null).
Are there any explanations as to why a variable instance would get updated without an associated process instance?
