JSF expression language question

Question

Hi, is it possible to write something like this:
<h:dataTable value="#{myControllerBean.persons}" var="person">
<h:column>
<h:outputText value="#{person.#(myControllerBean.selectedItem)}"/>
<h:column/>
</h:dataTable>
where i can dynamicly choose property for person bean.
myControllerBean.selectedItem is string, and depending on its value i want the column to be person.name or person.age, ....
I know this can be solved with columns for every case and rendered attribute, but i'm looking for some better solution :)
Thanks in advance.

Try this:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<c:set var="tmp" value="#{myControllerBean.selectedItem}"/>
Now set tmp in outputText as dynamic value:
<h:dataTable value="#{myControllerBean.persons}" var="person">
<h:column>
<h:outputText value="#{person[tmp]}"/>
<h:column/>
</h:dataTable>
