JSF expression inside another JSF expression

[barbarabxl]

Hello
I have a little problem. I have a list of maps List<Map<String,Waarde>>. For filling the maps I use a counter i, something like this:

  Map m = new HashMap();   
  m.put("waarde"+[B]i[/B], Waarde);   
  list.add(m);

To show the values on the screen I use a datatable, but to show the different objects Waarde in the maps, I need a counter in the name of the JSF expression, so a JSF expression inside another JSF expression, something like this:

<h:dataTable value="#{list}" var="_map">
   <a4j:repeat value="#{counter}" var="_i">
      <h:column>
         <h:outputText value="#{_map.waarde#{_i}.tekst}" />
      </h:column>
   </a4j:repeat>
</h:dataTable>

Has someone an idea how to deal with this?

Thanks a lot!

You don't need a counter to display values in the map.
Just loop through all the elements using the method entrySet which gives you all the entries.
You may need to create a getter style method in your backing bean so JSF can access it.

Thanks for your answer. I tried:

<h:dataTable value="#{waarden}" var="_map">

   <h:column>
      <h:outputText value="size #{_map.size}" />
   </h:column>

   <c:forEach items="#{_map.entrySet}" var="_mapje">
      <h:column>
         <h:outputText value="test #{_mapje.value.tekst}" />
      </h:column>
   </c:forEach>

</h:dataTable>

and the result was:

size 5
size 5
size 5

So there is a loop through the list with the 3 maps in it, but he doesn't loop through the maps.
