I have a SessionScoped bean which has a list of maps. I am attempting to get a <rich:dataTable> produced using <a4j:repeat>.

The list of maps is being populated correctly, although there is no dataTable output. From reading articles on stack-overflow, I think my problem may be occuring due to the life-cycle problems or my novice understanding of jsf with richfaces.

Using: Tomcat 7, JSF 2.1x - Mojarra, Richfaces 4.x

Here is what I have so 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 someone could point my in the correct direction, the help would be greatly appreciated!

Answer:

As stated below the solution is to instead use <c:forEach> and 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 all <rich:dataTable> has to contain columns - <rich:column>

Assuming you want to have dynamic table (the number of columns based on the length of the map) you will have to use <c:forEach> instead of <a4j:repeat>. I have answered a question about this a while ago, take a look.
