> as you can see, i don't use showButton=3D"true", because i need another f=
unctionality, i need erase input text before show popup window.
> I use JavaScript function "autocompleteChangeProvider" for extract select=
ed id.
> I use separate button(/img/cancel.png) for erase input text, as you can s=
ee this function just use Richfaces API.
>  =

> And a problem:
> if autocomplete.providerName not null and not empty(in rich:autocomplete)=
 and user clicks on show button(/img/arrow.png) than input text not erasing=
, but i called #{rich:component('provider-suggestion')}.setValue('') !!!
>  =

> I think i found a solution
> AutocompleteBase.js has this code:
> {code}
> rf.ui.AutocompleteBase =3D function(componentId, selectId, fieldId, optio=
ns) {  =

>         // call constructor of parent class  =

>         $super.constructor.call(this, componentId);  =

>         this.selectId =3D selectId;  =

>         this.fieldId =3D fieldId;  =

>         this.options =3D $.extend({}, defaultOptions, options);  =

>         this.namespace =3D this.namespace || "." + rf.Event.createNamespa=
ce(this.name, this.selectId);  =

>         this.currentValue =3D "";  =

>         this.tempValue =3D this.getValue();  =

>         this.isChanged =3D this.tempValue.length !=3D 0;  =

>         bindEventHandlers.call(this);  =

>     };
> {code}
> as you can see this.currentValue =3D "" so JS thinks that this.currentVal=
ue=3D"" so currentValue equal new value("" - empty string), so nothing happ=
ens.
> i replace this code by this:
> {code}
> rf.ui.AutocompleteBase =3D function(componentId, selectId, fieldId, optio=
ns) {  =

>         // call constructor of parent class  =

>         $super.constructor.call(this, componentId);  =

>         this.selectId =3D selectId;  =

>         this.fieldId =3D fieldId;  =

>         this.options =3D $.extend({}, defaultOptions, options);  =

>         this.namespace =3D this.namespace || "." + rf.Event.createNamespa=
ce(this.name, this.selectId);  =

>         this.currentValue =3D $(rf.getDomElement(fieldId)).val();  =

>         this.tempValue =3D this.getValue();  =

>         this.isChanged =3D this.tempValue.length !=3D 0;  =

>         bindEventHandlers.call(this);  =
