I have this autocomplete component:
{code}
<table>   =

   <tr>   =

      <td>   =

         <rich:autocomplete mode=3D"ajax" autocompleteMethod=3D"#{autocompl=
ete.autocompleteProviders}"   =

                            minChars=3D"0" var=3D"s" fetchValue=3D"#{s.real=
Name}" id=3D"provider-suggestion"   =

                            autofill=3D"false"   =

                            onselectitem=3D"autocompleteChangeProvider(even=
t.target)" style=3D"display: inline;"   =

                            layout=3D"table" value=3D"#{autocomplete.provid=
erName}" >   =

            <a4j:queue requestDelay=3D"500" ignoreDupResponses=3D"true" /> =
  =

            <h:column>   =

               <h:outputText style=3D"display:none;" value=3D"#{s.id}"/>   =

               <h:outputText style=3D"display:none;" value=3D"#{s.realName}=
"/>   =

            </h:column>   =

            <h:column>   =

               <h:outputText value=3D"#{s.name}" escape=3D"false"/>   =

            </h:column>   =

         </rich:autocomplete>   =

      </td>   =

      <td>   =

         <h:graphicImage value=3D"/img/arrow.png" onclick=3D"#{rich:compone=
nt('provider-suggestion')}.setValue('');#{rich:component('provider-suggesti=
on')}.showPopup();stopEvent(event);"   =

                         alt=3D""/>   =

         <h:graphicImage value=3D"/img/cancel.png"   =

                         onclick=3D"#{rich:component('provider-suggestion')=
}.hidePopup();#{rich:component('provider-suggestion')}.setValue('');autocom=
pleteChangeProvider(null);"   =

                         alt=3D"#{messages['pages.clear']}" title=3D"#{mess=
ages['pages.clear']}"/>   =

         <h:inputHidden id=3D"filter-provider-id" value=3D"#{autocomplete.p=
roviderId}"/>   =

      </td>   =

   </tr>   =

</table>
{code}
as you can see, i don't use showButton=3D"true", because i need another fun=
ctionality, i need erase input text before show popup window.
I use JavaScript function "autocompleteChangeProvider" for extract selected=
 id.
I use separate button(/img/cancel.png) for erase input text, as you can see=
 this function just use Richfaces API.
 =

And a problem:
if autocomplete.providerName not null and not empty(in rich:autocomplete) a=
nd 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, options=
) {  =

        // 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.createNamespace=
(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.currentValue=
=3D"" so currentValue equal new value("" - empty string), so nothing happen=
s.
i replace this code by this:

{code}
rf.ui.AutocompleteBase =3D function(componentId, selectId, fieldId, options=
) {  =

        // 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.createNamespace=
(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);  =

    };
{code}

and it works!
