Peter Ertl commented on WICKET-488:
-----------------------------------
I uploaded a patch implementing this improvement like Igor suggested (--
WICKET488_MoreComplexBehaviorForAutocompleter.patch)
There's a new method
CharSequence AbstractAutoCompleteRenderer#getOnSelectJavascript(Object item)
that returns custom javascript for each rendered item.
It will be executed upon selecting it in the autocompleter by either hitting
enter or clicking on it.
> Allow more complex behaviour for AutoCompleter component

> It would be nice to be able to modify the default behaviour of the ajax
> autocompleter component upon selection of an list item. this would make it a
> even more useful component and exceed it's capabilities beyond simple text
> replacement.
> current behaviour:
> ### snip : wicket-autocomplete.js line 93-97 ###
> case KEY_ENTER:
> if(selected>-1){
> obj.value=getSelectedValue();
> hideAutoComplete();
> hidingAutocomplete=1;
> ### eof snip ###
> Instead of having obj.value= being filled by the current text value it would
> be nice to have the option of specifying a js function callback to e.g. post
> back the selected value to the server. This way you could implement more
> complex behaviour, for example select a company address from a list and, on
> selecting it, send back the address id to the server which then would fill
> out street, house number, zip code and city.
> pseudo code:
> if selected
> if callback
> callback(value)
> else
> obj.value = current value
> end
> .....
> probably the right place for such a on-select contribution would be the
> autocomplete renderer.
