[jboss-user] [JBoss Seam] - Re: Assigning an Actor for SEAM-jBPM integration
OK, I was wondering whether something like a servlet filter could do the job, access the
Actor in the session context used by Seam, thus avoiding the need for the reference in the
JSF page.
I've tried petemuir's approach, but I must be missing something basic. I have a
stateless session bean:
| @Stateful
| @Scope(SESSION)
| @SecurityDomain("ctSecDom")
| @Name("todoList")
| public class TaskSession implements TaskSessionLocal, TaskSessionRemote {
|
| private static final Logger LOGGER = Logger.getLogger( TaskSession.class);
|
| @Out(scope=SESSION)
| private String currentUser;
|
| @Factory("currentUser")public void loginToSeam() {
| LOGGER.fatal( "loginToSeam() called" );
| String username = "testuser";
| currentUser = username;
| Actor.instance().setId(username);
| }
|
| ...
|
in my XHTML page, I have:
| <f:view>
| <h:form id="plist">
| <h:outputText value="Actor: #{todoList.currentUser}"
/>
| <div style="border-style: solid; border-width: 1px;
border-color: #0000ff; padding: 8px">
| <h1>Pooled To-Do Items</h1>
| ...
|
but when I enter the URL in the browser, I get the exception:

Shouldn't the valid of currentUser be outjected when the JSF needs to render it? What
is the exception message actually telling me?
Any assistance would be gratefully appreciated!
