Hi Thiago,
Have you tried adding the function as a JSONLiteral? And why are you
returning a function instead of having this function declared somewhere
else and just passing parameters to it in the JSONObject?
I am not, Tapestry is responsible for these hooks, we simply pass the
configuration or am I missing something?
I think we are not on the same page. I didn't quite understand your
comment... Tapestry's Autocompleter if recollection serves is based on
the underlying Scriptaculous autocompleter, right?
Yes.
So the Scriptaculous autocompleter has some hooks (updateElement &
afterUpdateElement) to trigger 'aftercompletion' events, but Tapestry's
implementation doesn't support these hooks, correct?
I guess so.
So how do I then enable these hooks without hacking it?
I'm sorry, I made a huge confusion in my last message.
From other posts, and past experience I recall adding a function
somewhere and just passing the parameters didn't work (though it really
should).
Examples please. :)
So far as I know only by overriding the mixin, or fudging the parameters
you can trigger these hooks, something like the following which extends
the mixin and rewires it a little:
public class ExtendedAutocomplete extends Autocomplete {
@Override
protected void configure(JSONObject config)
{
config.put("afterUpdateElement", new
JSONRaw("onSelectFromAutocomplete"));
...
}
I guess this should work, but I don't know about the client-side part. And
JSONLiteral already does what your proposed JSONRaw does.
Anyway, you can file a JIRA for this being added to Autocomplete itself.
