Description

when AutoCompleteTextField is reset to a 0 length input String (using backspace for exemple) Wicket.Ajax.invokePostCallHandlers(); is not invoke. it is a problem cause Wicket.Ajax.registerPreCallHandler is called.

when these events are used to show ajax busy indicator for exemple, it stay on busy state.

i think that
(solution 1) pre and post should be called on 0 input string length call
or
(solution 2) pre and post should not be called (there is no ajax call after all)

but not pre called et not post.

for case 1 (pre and post, it can be fixed quickly in wicket-autocomplete.js function doUpdateChoices(resp)

adding

if ((Wicket.Focus.getFocusedElement() != input) || !cfg.showListOnEmptyInput && (input.value==null || input.value=="")) {
hideAutoComplete();
Wicket.Ajax.invokePostCallHandlers(); // line to be added
return;
}

i don't have enought insight in wicket-ajax for proposing a fix for solution 2

thanx
