I'm experiencing this same problem, even after synching with the latest CVS rev.
Here's a really simple set of classes that should help you recreate the problem:
TestService EJB interface...
package com.testcase.service;
|
| import javax.ejb.Local;
|
| @Local
| public interface TestService {
| public Object getObject(Long objectId);
|
| }
TestService EJB impl...
package com.testcase.service;
|
| import javax.ejb.Stateless;
|
| @Stateless
| public class TestServiceBean implements TestService {
|
| public Object getObject (Long objectId) {
| return new Object();
| }
| }
TestObject EJB Seam Component interface...
package com.testcase.faces;
|
| import javax.ejb.Local;
|
| @Local
| public interface TestObject {
| public Object getObject();
|
| public void destroy();
| }
package com.testcase.faces;
|
| import static org.jboss.seam.ScopeType.EVENT;
|
| import javax.ejb.EJB;
| import javax.ejb.Remove;
| import javax.ejb.Stateful;
|
| import org.jboss.seam.annotations.Destroy;
| import org.jboss.seam.annotations.Logger;
| import org.jboss.seam.annotations.Name;
| import org.jboss.seam.annotations.Scope;
| import org.jboss.seam.annotations.Unwrap;
| import org.jboss.seam.log.Log;
|
| import com.testcase.service.TestService;
|
| /**
| * Stateful Seam component named "TesObject", scoped to the EVENT (life of
the
| * request) context.
| *
| */
| @Stateful
| @Scope(EVENT)
| @Name("TestObject")
| public class TestObjectBean implements TestObject {
|
| @Logger
| private Log log;
|
| @EJB
| private TestService _testService;
|
| @Unwrap
| public Object getObject() {
| Object object = _testService.getObject(new Long(1));
| log.debug("got object");
| return object;
| }
|
| @Destroy @Remove
| public void destroy() {}
| }
TestPage.xhtml...
<?xml version="1.0" encoding="utf-8"?>
| <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
|
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
| <ui:composition xmlns="http://www.w3.org/1999/xhtml"
| xmlns:ui="http://java.sun.com/jsf/facelets"

| xmlns:f="http://java.sun.com/jsf/core"
| xmlns:c="http://java.sun.com/jstl/core"
| template="/templates/DefaultPage.xhtml">
| <ui:define name="body">
|
| #{TestObject.object}
|
| </ui:define>
| </ui:composition>
Deploy that in a webapp, call up the TesPage.xhtml and watch for this in your server
