> I try repeat:
> I have this autocomplete component:
> {code}
> <table>
> <tr>
> <td>
> <rich:autocomplete mode="ajax"
> autocompleteMethod="#{autocomplete.autocompleteProviders}"
> minChars="0" var="s" fetchValue="#{s.realName}"
> id="provider-suggestion"
> autofill="false"
>
> onselectitem="autocompleteChangeProvider(event.target)" style="display:
> inline;"
> layout="table"
> value="#{autocomplete.providerName}" >
> <a4j:queue requestDelay="500" ignoreDupResponses="true" />
> <h:column>
> <h:outputText style="display:none;" value="#{s.id}"/>
> <h:outputText style="display:none;" value="#{s.realName}"/>
> </h:column>
> <h:column>
> <h:outputText value="#{s.name}" escape="false"/>
> </h:column>
> </rich:autocomplete>
> </td>
> <td>
> <h:graphicImage value="/img/arrow.png"

>
> alt=""/>
> <h:graphicImage value="/img/cancel.png"
>
> onclick="#{rich:component('provider-suggestion')}.hidePopup();#{rich:component('provider-suggestion')}.setValue('');autocompleteChangeProvider(null);"
>
> alt="#{messages['pages.clear']}"
> title="#{messages['pages.clear']}"/>
> <h:inputHidden id="filter-provider-id"
> value="#{autocomplete.providerId}"/>
> </td>
> </tr>
> </table>
> {code}
> as you can see, i don't use showButton="true", because i need another
> functionality, 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 problem:
> if autocomplete.providerName not null and not empty(in rich:autocomplete) and
> user clicks on cancel button(img/cancel.png), then after that, if user clicks
> on show button(/img/arrow.png) popup not showing, user must clicks twice on
> this button.
> *This problem shows if i use showButton from rich:autocomplete instead my
> show button.*
> I think i found a solution of this problem:
> Autocomplete.js has this code:
> {code}
> var onChangeValue = function (event, value, callback) {
> selectItem.call(this, event);
>
> // value is undefined if called from AutocompleteBase onChange
> var subValue = (typeof value == "undefined") ? this.__getSubValue() :
> value;
> var oldValue = this.value;
> this.value = subValue;
>
> if ((this.options.isCachedAjax || !this.options.ajaxMode) &&
> this.cache && this.cache.isCached(subValue)) {
> ...
> } else {
> if (event.keyCode == rf.KEYS.RETURN || event.type == "click") {
> this.__setInputValue(subValue);
> }
> if (subValue.length >= this.options.minChars) {
> if ((this.options.ajaxMode || this.options.lazyClientMode) &&
> oldValue != subValue) {
> callAjax.call(this, event, callback);
> }
> } else {
> if (this.options.ajaxMode) {
> clearItems.call(this);
> this.__hide(event);
> }
> }
> }
> };
> {code}
> for show popup this must be true:
> {code}
> oldValue != subValue
> {code}
> but in this part of code
> oldValue is ''(empty string) and subValue is ''(empty string),
> so this condition
> {code}
> oldValue != subValue
> {code}
> return false!
>
> i replace this code by this:
> {code}
> var onChangeValue = function (event, value, callback) {
> selectItem.call(this, event);
>
> // value is undefined if called from AutocompleteBase onChange
> var subValue = (typeof value == "undefined") ? this.__getSubValue() :
> value;
> var oldValue = this.value;
> this.value = subValue;
>
> if ((this.options.isCachedAjax || !this.options.ajaxMode) &&
> this.cache && this.cache.isCached(subValue)) {
> ...
> } else {
> if (event.keyCode == rf.KEYS.RETURN || event.type == "click") {
> this.__setInputValue(subValue);
> }
> if (subValue.length >= this.options.minChars) {
> if ((this.options.ajaxMode || this.options.lazyClientMode) &&
> (oldValue != subValue || (oldValue === '' && subValue === ''))) {
> callAjax.call(this, event, callback);
> }
> } else {
> if (this.options.ajaxMode) {
> clearItems.call(this);
> this.__hide(event);
> }
> }
> }
>
> };
> {code}
> so, than oldValue='' and subValue=='' callAjax.call will be called and popup
> will be showing.
