JSF (richfaces) component + JSTL forEach

Question

Hi,
I'm using MyFaces implementation of JSF 1.2, together with RichFaces components, and inside a <rich:dataTable>'s <rich:column> I want to iterate over a Set, which is a property of the variable of the dataTable. Something like
<rich:dataTable var="myvar">
<rich:column>
   <c:forEach var="innerVar" values="${myVar.mySet}"
       ${innerVar}
   </c:forEach>
</rich:column
</rich:dataTable>But it doesn't work. myVar seems to be empty for c:forEach. The odd thing is that if I place the following code inside the <rich:column>
<c:if test="${empty myVar">
        ${myVar.class.name}
</c:if>the name of the class is outputted. I also tried # isntead of $, with no success.
I tried iterating over a list in a declared backing bean, and it worked fine. So the question would go like this - how do I make this variable accessible for jstl tags' expressions.

Answer 1

and why wouldn't you use a getter which does the transformation from Set to List just for the UI layer:
public List<InnerVar> getInnerVarList() {
   // transform Set into a List<> here
} and then in the UI:
<rich:column>
   <ui:repeat var="innerVar" values="#{innerVarList}"
       #{innerVar}
   </ui:repeat>
</rich:column>
