POJO does not get outjected in the page context as expected
-----------------------------------------------------------

                 Key: JBSEAM-2615
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2615
             Project: JBoss Seam
          Issue Type: Bug
    Affects Versions: 2.0.1.GA
         Environment: Seam 2.0.1, RichFaces 3.1.4, JBoss AS 4.2, Sun JSF 1.2 RI, Facelets
            Reporter: fredatwork


I described what I believe is a bug regarding the seam page context. See http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4128529 .

In brief, a POJO with page context got not outjected as expected.

Please consider the following sample (code id pasted below) and use it as described in the forum topic referenced above.

View sample2.seam first in your favorite browser. Once the start button is pressed, sample2next.xhtml renders a counter at 0 . However, the Sample2Action.init action initiated this counter to 1 . Everything happens as the completion of Sample2Action.init does not outject the POJO Sample2Context to the PAGE context, and the action Sample2Action.refresh retrieves a newly created object. 

Same thing happens with the following modifications to the Sample2Action component (POJO object is not auto-created, init method does it explicitely):

// Page context object
@In(value="Sample2Context", scope=ScopeType.PAGE, required=false)
@Out(value="Sample2Context", scope=ScopeType.PAGE, required=true)
private Sample2Context context;

/**
 * @see sample2.Sample2Local#init()
 */
public void init() {
	context = new Sample2Context ();
	context.increment();
	facesMessages.add(FacesMessage.SEVERITY_INFO, "Initiated page context " + context);
	System.out.println("Initiated page context " + context);
}

PS: I keep a safe-copy of Eclipse projects with the sources below, in case someone needs them (cannot attach zip files to this bug report)
