jboss seam 1.2.1
I am having trouble understanding how bijection work with jbpm. Here is a
simple jpdl:
| <process-definition name="MyWorkflow">
|
| <start-state name="start">
| <transition to="decide"></transition>
| </start-state>
|
| <decision name="decide" expression="#{myManager.result}">
| <transition to="assigntask" name="assigntask"></transition>
| <transition to="end" name="end"></transition>
| </decision>
|
| <task-node name="assigntask">
| <task name="Evaluate">
| <assignment actor-id="adminuser"></assignment>
| </task>
| <transition to="end" name="cancel"></transition>
| <transition to="decide" name="retry"></transition>
| </task-node>
|
| <end-state name="end"></end-state>
|
| </process-definition>
|
Notice that the decision task calls #{myManager.decide} which a SFSB:
| @Stateful
| @Name ("myManager")
| public class MyManagerImpl implements MyManager,
| Serializable {
|
| private static final long serialVersionUID = 1L;
|
| @Logger
| private Log LOG;
|
| @PersistenceContext (type = PersistenceContextType.EXTENDED)
| private EntityManager entityManager;
|
| @In (required = false)
| @Out (scope = BUSINESS_PROCESS, required = true)
| private Long id;
|
| @CreateProcess(definition = "MyWorkflow")
| public void begin() {
| id = new Long(10);
| }
|
| public String getResult() {
| // NPE :-(
| // why doesnt id get injected?
| int x = id.intValue();
| }
|
| @Remove
| @Destroy
| public void destroy() {
| }
| }
|
I get a NPE in getResult() when it is called by jBPM. How come id never gets
injected back?
I set logging to TRACE on org.jboss.seam.Component and I get the "injecting
dependencies of" message when begin() is called. But I DONT see the same
messages when the jBPM task node executes the getResult() expression.
Am I missing something in a config file?
Thanks in advance.
