Frank Klein Koerkamp commented on WICKET-2032:
----------------------------------------------

Also add call hideIndicator(). See example beneath

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

> 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
