No, you're right. I was confused. Now I do think I know why it doesn't work
though.
In your jwc file, you have specified the class which implements your
component, and is the place to go look for methods, etc.
<component-specification class="...
When you define a sub-component, like this;
<component id="editClient" type="DirectLink">
<binding name="listener" value="listener:editClient"/>
</component>
Tapestry will look for the editClient() or editClient(IRequestCycle cycle)
(I think) in the class specified.
what I do when I want dynamic listeners, or what you could call them, is to
let the listener be a parameter to my component, like;
<parameter name="callback"/>
and then in the component class have
public abstract IActionListener getCallback();
public abstract void setCallback(IActionListener l);
And then I use this somwhere in the class like;
IActionListener c = getCallback();
c.actionTriggered(this, cycle);
Or maybe as an parameter to something else, like you have in your component;
<binding name="listener" value="callback"/>
Cheers,
