[jboss-user] [JBoss Seam] - Injecting Business Process context scoped variables

Hi, I've defined a workflow that is started by a method called "receive(...)" (annotated with @CreateProcess). In this method I outject a variable named "workEffortId" into the Business Process context. My jPDL is rather short (start-node -> transition -> task-node -> transition -> end-node). In the 1st transition I have defined an action expression which calls a method called "assignToTimeSheet". In this method I inject variable "workEffortId" (Business Process context), but it is always null! If I call "assignToTimeSheet" in the 2nd transition, "workEffortId" gets the value that was outjected in "receive(...)". So, my assumption is that, because jBPM performs a transaction commit at the 1st wait-state (in this example at the task-node) and "assignToTimeSheet" is called before, Seam tries to read data that have not been committed yet, which results to a null value. Alternatively using an async node is not yet supported by Seam (see http://jira.jboss.com/jira/browse/JBSEAM-161). Does anybody has an idea how to solve this? Thx, Manuel PS. See my example code below (excerpts).
