-------------------------------------
Summary: Autocomplete: ignored API call .setValue('')
Key: RF-13306
URL: https://issues.jboss.org/browse/RF-13306
Project: RichFaces
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Affects Versions: 4.3.4
Reporter: alexey plotnikov
All described here https://community.jboss.org/thread/233973
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"
onclick="#{rich:component('provider-suggestion')}.setValue('');#{rich:component('provider-suggestion')}.showPopup();stopEvent(event);"
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 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 = function(componentId, selectId, fieldId, options) {
// call constructor of parent class
$super.constructor.call(this, componentId);
this.selectId = selectId;
this.fieldId = fieldId;
this.options = $.extend({}, defaultOptions, options);
this.namespace = this.namespace || "." +
rf.Event.createNamespace(this.name, this.selectId);
this.currentValue = "";
this.tempValue = this.getValue();
this.isChanged = this.tempValue.length != 0;
bindEventHandlers.call(this);
};
{code}
as you can see this.currentValue = "" so JS thinks that this.currentValue="" so
currentValue equal new value("" - empty string), so nothing happens.
i replace this code by this:
{code}
rf.ui.AutocompleteBase = function(componentId, selectId, fieldId, options) {
// call constructor of parent class
$super.constructor.call(this, componentId);
this.selectId = selectId;
this.fieldId = fieldId;
this.options = $.extend({}, defaultOptions, options);
this.namespace = this.namespace || "." +
rf.Event.createNamespace(this.name, this.selectId);
this.currentValue = $(rf.getDomElement(fieldId)).val();
this.tempValue = this.getValue();
this.isChanged = this.tempValue.length != 0;
bindEventHandlers.call(this);
};
{code}
and it works!
