jsf 2 - <rich:dataTable> from listOfMaps -


i have sessionscoped bean has list of maps. attempting <rich:datatable> produced using <a4j:repeat>.

the list of maps being populated correctly, although there no datatable output. reading articles on stack-overflow, think problem may occuring due life-cycle problems or novice understanding of jsf richfaces.

using: tomcat 7, jsf 2.1x - mojarra, richfaces 4.x

here have far; 

<rich:datatable value="#{mybean.mymap}" var="map">      <a4j:repeat value="#{mybean.mymap[0].keyset().toarray()}" var="key">         #{map[key]}     </a4j:repeat>  </rich:datatable>

if point in correct direction, appreciated!

answer:

as stated below solution instead use <c:foreach> , use <rich:columns>.

solution:

<rich:datatable value="#{querybean.test}" var="map">     <c:foreach items="#{querybean.test[0].keyset().toarray()}" var="key">          <rich:column style="text-align:left; width:auto;">             <f:facet name="header">                 <h:outputtext value="#{key}" />             </f:facet>             <h:outputtext value="#{map[key]}" />         </rich:column>      </c:foreach> </rich:datatable>

first of <rich:datatable> has contain columns - <rich:column>

assuming want have dynamic table (the number of columns based on length of map) have use <c:foreach> instead of <a4j:repeat>. have answered question while ago, take look.
