Overriding onEvent to update choices side of Palette
I just would like to add to the choices side of the palette the selection
made by the user (in my case through an autocomplete textfield).
This all exectutes fine, but nothing gets added.
Is my ...add(this.getChoicesComponent()) the correct way to accomplish what
I need ?
( I am overriding the onEvent of the Palette)
@Override
public void onEvent(IEvent<?> event) {
super.onEvent(event);
if (event.getPayload() instanceof MyAutoCompleteUpdate){
MyAutoCompleteUpdate update = (MyAutoCompleteUpdate)event.getPayload();
update.getTarget().add(this.getChoicesComponent());
}
}

I guess you have add those new "choices" to the palette before "repainting

What I mean AJAX request target (ART) will trigger an event with ART as
payload. See AjaxRequestHandler#respond...
page.send(app, Broadcast.BREADTH, this);
you could place a flag of RequestCycle to identify AjaxFormUpdatingBehavior
was triggered and use that event do the repainting.

Re: Overriding onEvent to update choices side of Palette
Posted by grazia <Gr...@gmail.com>.
Let me give you more context:
my page consists of:
- a lazy loading autocompletetextfield
- a form containing the palette
By selecting an option in the autocomplete, the left side of the palette
(choices side) should display that selection made in the autocomplete.
So, I have so far managed to add a AjaxFormUpdatingBehavior to the
autocomplete, which sends the event to the palette ( using
Component.*send<http://wicket.apache.org/apidocs/1.5/org/apache/wicket/Component.html#send%28org.apache.wicket.event.IEventSink,%20org.apache.wicket.event.Broadcast,%20T%29>
*(IEventSink<http://wicket.apache.org/apidocs/1.5/org/apache/wicket/event/IEventSink.html>
sink,
Broadcast<http://wicket.apache.org/apidocs/1.5/org/apache/wicket/event/Broadcast.html>
type,
T payload) ). For the palette to receive the event, I override the onEvent
method I showed you.
Now, the onEvent receives the AjaxRequestTarget, but
target.add(this) (where "this" is the palettte) does not do anything.
I tried:
target.add(this.getChoicesComponent()) and does not anything either.
"Why not use the event triggered by the ART directly. " could you please
explain ?

Hi,
It is difficult to understand what you are doing... Are you in the middle
of an AjaxRequestTarget(ART)? If that what
update.getTarget().add(this.getChoicesComponent());
means? Why not use the event triggered by the ART directly.
