Hi!

I'm currently stuck with a process/reRender problem using dynamic number of columns with rich:dataTable/rich:columns.

As you can see in the code below, I have an a4j:commandLink in the first colum of a table to allow editing of that row. If the button is clicked, I need to refesh all cells of one row that are generated by the rich:columns element (and not that easy to refernce). After editing, I need to process these cells - or the whole row. But I cannot get the row addressed (no row-id is generated) and I don't know how to reference the dynamic number of cells.

How can I construct a process/reRender-expression that references all generated cells of the corresponding row or the whole row?

<a4j:commandLink id="editRow"
 actionListener="#{row.setEdit(true)}"
 ajaxSingle="true"
 process="????????"
 reRender="action,????????">

<rich:dataTable value="#{tableDataModel}" var="row" id="table" styleClass="data" rows="5">

<rich:column styleClass="actions" id="action">
 <f:facet name="header">
 Actions
 </f:facet>
 <a4j:commandLink rendered="#{!row.edit}" id="editRow"
 actionListener="#{row.setEdit(true)}"
 ajaxSingle="true"
 process="????????"
 reRender="action,????????">
 <h:graphicImage value="resource:///img/ico_edit.gif" styleClass="abstand"/>
 </a4j:commandLink>
</rich:column>

<rich:columns value="#{tableDataModel.columns}"
 var="column"
 index="index"
 id="???? - to be set - or not to be set ????"
 styleClass="#{row.edit ? 'edit' : ''}">
 <f:facet name="header">
 <h:outputText value="#{column.columnDetail.label()}" />
 </f:facet>
 <h:outputText value="ColumnIndex: #{index}" />
</rich:columns>

</rich:dataTable>
