Form doesn't get refreshed

[jvarma]

Hi,

I am new user of Ajax4jsf rich faces. I am trying to work out whether it can be used in an existing project done uding JSF(myfaces 1.1.3).I have downloaded richfaces3.1.4 into my project.
I am using a4j:support in a drop down list of a data table. According to the value change of the drop down I need to display a check box . Here is my code:

JSP:

<t:dataTable id="workData" value="#{DefineQuoteBean.workQtDetail}" var="wkQtDetail"
border="0" columnClasses="deptColm,"
preserveDataModel="false" rowGroupStyle="border-bottom:gold;border-bottom-style:solid;
border-bottom-width:2px;vertical-align:top" style="width:100%">
<t:column>
<f:facet name="header">
<h:outputText id="vt" value="#{msg.vat}" />
</f:facet> <a4j:region>
<h:selectOneMenu id="vat" value="#{wkQtDetail.vat}"
disabled="#{DefineQuoteBean.readonly}"
valueChangeListener = "#{DefineQuoteBean.changeVat}" ><%-- onchange="submit();" limitToList="true" requestDelay="3600"--%>
<f:selectItem itemValue="none" itemLabel="Select" />
<f:selectItem itemValue="tbc" itemLabel="TBC" />
<f:selectItem itemValue="fullRt" itemLabel="Std Rated" />
<f:selectItem itemValue="zero" itemLabel="Zero Rated" />
<f:selectItem itemValue="exempt" itemLabel="Exempt" />
<a4j:support event="onchange" actionListener="#{DefineQuoteBean.changeSelection}" reRender="outputselectonemenu" >
</a4j:support>
</h:selectOneMenu> </a4j:region>
</t:column>
</t:dataTable>

<a4j:outputPanel ajaxRendered="true" id="outputselectonemenu">
<h:selectBooleanCheckbox id="displayVat" value="#{DefineQuoteBean.displayVat}"
rendered="#{DefineQuoteBean.renderDispVat}" valueChangeListener = "#{DefineQuoteBean.changeSelection}"
 onclick="submit();"/> </a4j:outputPanel>

Bean:

public void changeSelection(javax.faces.event.ActionEvent event) throws ServiceException{
 //code for turn on the check box and command button
 Logger.getLog().debug("Changed ! ! ! : "+this.qtNo);
 }

My Problem :

When the value of the drop down changed, it executes the action event and 'Changed!!!' and the value being diplayed. But the check box doesn't displayed. I don't want the whole form to be reloaded. I just want the checkbox to be dosplayed without getting refreshed the rest of the page.

Can anyone tell me how can I solve this problem ?

Thanks,

Please help me to identify where I am going wrong.

I have tried using the h:inputText and h:outputText outside the datatable and it worked !! Is the datatable is making probem ?

I sort this out.

Following changes made :

<a4j:support event="onchange"
actionListener="#{DefineQuoteBean.changeSelection}" reRender="output" > <%-- return confirm('Are you sure you want to change?') onsubmit="alert('VAT change');"--%>
<a4j:ajaxListener type="org.ajax4jsf.ajax.ForceRender"/>
</a4j:support>
