Form Listner Problem

Message-ID <[email protected]> 
I am having problems binding to a form listener method.  From the
example in the "component reference" I have the following
page-specification that has two components to be wraped in a Form
component.  Also it might be important to know that this page is
"wrapped" within multiple framesets.  Does anyone have an idea why the
ONGL expressing "listeners.login" does not work ?


<?xml  version="1.0"  encoding="UTF-8" ?>
<!DOCTYPE  page-specification  PUBLIC  "-//Howard Lewis Ship//Tapestry
Specification 1.3//EN"  "http://tapestry.sf.net/dtd/Tapestry_1_3.dtd" >

<page-specification  class="_cwg$cwg.Woven.WovenFrame" >

    <component  id="login"  type="Form" >
        <binding  name="listener"  expression="listeners.login" />
    </component>

    <component  id="username"  type="TextField" >
        <binding  name="value"  expression="visit.username" />
    </component>

    <component  id="password"  type="TextField" >
        <binding  name="value"  expression="visit.password" />
        <binding  name="hidden"  expression="true" />
    </component>

<!-- -->

    <component  id="tShell"  type="Shell" >
        <static-binding  name="title" >My Title from
SideBar.page</static-binding>
    </component>

    <component  id="tBody"  type="Body" />

</page-specification>



Folowing is the Java program.  I hava sub-classed WovenFrame from
BasePage.


package _cwg$cwg.HomePage ;

import _cwg$cwg.Woven.WovenFrame ;

import net.sf.tapestry.IRequestCycle ;

public class SideBar extends _cwg$cwg.Woven.WovenFrame {

    public void login (IRequestCycle cycle) {
        Visit visit = (Visit) getVisit () ;
    }
}
