Hi. We are using WiQuery in our application to attach some behaviors to some
components. For example a resize behavior to react on the component being
resized. I added some debug logging and I see that when we switch panels
(through Ajax) all event listeners for the components on the new panel are
added, but the old ones from the panel being replaced are never removed. So the
list of event handlers just grows and grows...
We register event listeners in the statement method of the WiQuery behavior,
like this:
public abstract class BaResizeEventBehavior extends WiQueryAbstractBehavior {
// ...
@Override public JsStatement statement() {
return new JsQuery(getComponent()).$().chain("resize", new JsScope() {
@Override public void execute(JsScopeContext aScopeContext) {
// event listener implementation here
}
});
}
}
This will generate Javascript code that looks like this:
$('#componentId').resize(function() {
// event listener implementation here
});
This code will register a jQuery event on the component with id 'componentId'.
However when this component disappears from the page, I would like this event
handler to be unbound again, but that does not happen.
Any ideas?
Thanks,

P.S:
This is cross-posted to
http://groups.google.com/group/wiquery-plugins/browse_thread/thread/aaceac38d60adbcf
because that group seems to have hardly any traffic... Hopefully one of the
Wicket gurus here knows a bit about WiQuery as well? Although maybe this
question can be formulated for Wicket as well as also there when doing Ajax we
need to clean up after components when they are removed from the page right?
