Hello all,
I'm trying to create a seam managed Action Handler for a jbpm node ( not a task
node ). I want to inject a variable into this action which is outjected in a
another SLSB.
My process definition:
|
| <?xml version="1.0"?>
| <process-definition name="inkless">
| <start-state name="start">
| <transition name="" to="node1"></transition>
| </start-state>
| <end-state name="end1"></end-state>
| <node name="node1">
| <action name="action1" expression="#{bar.foo}"/>
| <transition name="" to="end1"></transition>
|
| </node>
|
| </process-definition>
|
|
The code that creates the process and Outjects a Context variable:
|
| @Stateless
| @Name("inklessProcessManager")
| @Interceptors(SeamInterceptor.class)
| public class InklessProcessManagerImpl implements InklessProcessManager {
|
| @Out(scope=ScopeType.BUSINESS_PROCESS, value="foo") Integer someThing;
|
| @CreateProcess(definition="inkless")
| public void startProcess() {
| someThing=new Integer(5);
| }
|
| }
|
|
And now my actionhandler which is called in the process definition:
|
| @Stateless
| @Name("bar")
| @Interceptors(SeamInterceptor.class)
| public class BlahBlahActionHandler implements IActionHandler {
|
| /* (non-Javadoc)
| * @see com.melexis.inkless.IActionHandler#foo()
| */
| @In(value="foo", scope=ScopeType.BUSINESS_PROCESS) Integer foe;
|
|
| @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
| public void foo(){
| System.out.println("Foooooooooooooo");
| System.out.println(foe);
| }
|
| }
|
|
And finally the exception i receive:
|
| Caused by: javax.ejb.EJBException: org.jboss.seam.RequiredException: In
attribute requires non-null value: bar.foo

I'm just starting out with jboss seam so it might be my own incompetence, but i
think i understood the documentation correctly.
Can someone point out what i'm doing wrong? Thank you.
Best regards,
Jo
