a4j:repeat does not work in rich:datatable

1) I tried to replace t:columns with a4j:repeat, but it does not work in rich:datatable. same for ui:repeat.

 <rich:dataTable var="row" value="#{bean.data}">
 <rich:column>
 <f:facet name="header">
 <t:outputText value="Groupe" />
 </f:facet>
 <t:outputText value="#{row.group}" />
 </rich:column>
 <rich:column>
 <f:facet name="header">
 <t:outputText value="Label" />
 </f:facet>
 <t:outputText value="#{row.libelle}" />
 </rich:column>

 <a4j:repeat value="#{bean.columnHeaders}" var="day">
 <rich:column>
 <f:facet name="header">
 <t:outputText value="#{day.value}" >
 <f:convertDateTime pattern="dd/MM/yy " />
 </t:outputText>
 </f:facet>
 </rich:column>
 </a4j:repeat>
 </rich:dataTable>
 <a4j:repeat value="#{bean.columnHeaders}" var="day">
 <t:outputText value="#{day.value}" >
 <f:convertDateTime pattern="dd/MM/yy "/>
 </t:outputText>
 </a4j:repeat>

2) how much rich:columngroup can be used in a rich:datatable? Could we mix rich:column with rich:columngroup?

a4j:repeat, ui:repeat or any other similar JSF components will not work in such role. See my answer at http://jboss.com/index.html?module=bb&op=viewtopic&t=106113

rich:columnGroup is useful when you want to apply some attributes (style* or on*) on the set of columns.
rich:columnGroup is very useful to build complex header or footer (as soon as facets do not accept several rich:column as children).
See the beginning of an incomplete article about rich:dataTable :
http://labs.jboss.com/wiki/RichFacesArticleDataTable

You can mix rich:column and rich:columnGroup, as well as h:column, t:column, t:columns

hi sergey,

thanks for your reply.

1) I have read your post. you suggest use c:foreach to replace t:columns? i dont like c:foreach very much. and In the developper guide of facelets they suggest "The repeat tag should be used in almost all cases instead of the c:forEach to iterate over content with JSF".

2)I think your model columngroup is a little complex to use. for nested column , the ADFFaces has a better approach. I will be happy if i could have same thing in rich:datatable.
<af:column> <f:facet name="header"> </f:facet> <af:column> <f:facet name="header"> </f:facet> ....... </af:column> <af:column> <f:facet name="header"> </f:facet> ...... </af:column> </af:column>
