[Tapestry-developer] Form Listner Problem

Mon, 25 Nov 2002 14:50:21 -0800

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 () ;
    }
}
