h:dataTable combined with nested a4j:outputPanel & a4j:suppo

[gjeudy]

Hi,

I am using richfaces 3.2.0 with seam 2.0.1 in JBoss 4.2.2 AS. I cannot get AJAX validation working when nested a4j:outputPanel & a4j:support in a h:dataTable.

<h:form id="domainInstancesForm">
 <h:dataTable var="domInstance"
 value="#{activeDomain.referenceDomainInstances}">
 <h:column>
 <f:facet name="header">
 <h:outputText value="Valid from date" />
 </f:facet>
 <a4j:outputPanel id="outpanevalidFromDate" >
 <div class="entry">
 <s:label styleClass="label #{invalid?'errors':''}">
 <s:span styleClass="required">*</s:span>
 </s:label>
 <span class="input #{invalid?'errors':''}">
 <s:validateAll>
 <h:inputText id="validFromDate" value="#{domInstance.validityPeriod.validFromDate}" required="true">
 <a4j:support event="onblur" reRender="outpanevalidFromDate">
 </a4j:support>
 </h:inputText>
 </s:validateAll>
 </span>
 <s:message styleClass="errors"/>
 </div>
 </a4j:outputPanel>
 </h:column>
 </h:dataTable>
 </h:form>

I turned on a4j:log debug output and I get the following suspicious entry:

warn[13:54:27,578]: Node for replace by response with id domainInstancesForm:j_id90:outpanevalidFromDate not found in document

I verified in the generated HTML and the corresponding a4j:outputpane expressed as an HTML span tag yields the following id: domainInstancesForm:j_id90:0:outpanevalidFromDate.

This solution works fine in a regular form with no h:dataTable.

So my question here is a4j:support useable in a dataTable context? It seems to me that it is not aware of the dataTable rowIndex which is used to generate the outputpane id. ex: domainInstancesForm:j_id90:0:outpanevalidFromDate.

Thanks,

I'm having issues with a4j:support in a datatable as well.
Like Guillaume I have a4j:support in a table but am using a rich:dataTable and have my a4j:support tag attached to a commandLink in a table row:

<rich:dataTable value="#{Bean.selectedUsers}" var="user">
 <rich:column>
 <f:facet name="header">
 <h:outputText value="Username" />
 </f:facet>
 <h:outputText value="#{user.username}" />
 </rich:column>
 <rich:column>
 <h:commandLink value="Remove">
 <a4j:support event="onclick" reRender="thisPanel" action="#{Bean.unselectUser}" actionListener="#{user.selectUserItem}" />
 </h:commandLink>
 </rich:column>
</rich:dataTable>

I have a combobox control inside this frame which has the same behaviour and backing code as this (except that it adds users to the table) and is working 100%.
The code above is also working for me, except that the reRender never happens - I can see that my collections are updated properly when the actions are fired, but they don't update until I trigger a screen rerender through a different control. The only difference I can see is that this a4j:support is inside a dataTable.

Are we both coming up against a bug in a4j:support or data tables?

Yikes, minutes later I solved my own problem myself - I changed my h:commandLink to a4j:commandLink and things are working as expected.

Sorry to Guillaume for butting into his issue - clearly we weren't having the same problem!
