Subject: Rendering form submit response with the same page.
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Content-Transfer-Encoding: 7bit

I have a page which I want to use to display a form and some results 
after the form is submitted.

After the form listener does some work I want to set a value on the page 
and show the same page again.  To do this I created a listener on the 
page class and inject a page of the same type as the current page and 
set the property that I want:

@InjectPage("TestPage")
public abstract TestPage getTestPage();

public abstract Object getObject();
public abstract void setObject(Object o);

public IPage doSubmit() {
    TestPage tp = getTestPage();
    tp.setObject(...);
    return tp;
}

This doesn't work.  From what I can tell tapestry doesn't create a new 
instance of the page and instead gets the same instance that it used to 
handle the form submit with all of the values reset.  I tried just 
calling setObject() on the current instance and returning "this" but 
that doesn't work either.

Any suggestions?  I'm doing this within a portlet in case that matters.

Thanks
-Aj
