Description

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:

1. 1. 1. snip : wicket-autocomplete.js line 93-97 ###
         case KEY_ENTER:
         if(selected>-1){
         obj.value=getSelectedValue();
         hideAutoComplete();
         hidingAutocomplete=1;
      2. 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.
