I haven't did this (dinamically nested columns) but If you are using
facelets or JSF 1.2 try using c:forEach and post the results, maybe this
solve your issue.

This is indeed what I want to do. However, I need to have data in one column
("counters") that is a List of data of my var. So I try to iterate this
list... which results in an exception:
java.lang.IndexOutOfBoundsException: Index: 5, Size: 5

This is what I did:
<tr:table id="overview" value="#{backingBean.dataModel}" var="row">
<tr:column>
<f:facet name="header">
<tr:outputText value="Date"/>
</f:facet>
<tr:outputText value="#{row.date}"/>
</tr:column>
<tr:column width="20%" headerText="Counters">
<tr:column>
<tr:iterator value="#{row.counters}" var="counter">
<tr:column headerText="id">
<tr:outputLabel
value="#{counter.valueString}"/>
</tr:column>
</tr:iterator>
</tr:column>
</tr:column>

You can use nested columns, for details search for "Column Groups" in
the tag documentation[1] and in the developer guide[2].
