> 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.
