[Trinidad] tr:table within tr:table

[Francisco Passos]

Hello there.

I'm attempting to use a tr:table within another one and the second one
doesn't show. I'm trying to present a list of values, where each value may
have a list of different values. So I was aiming for something like

Column 1 | Column 2
---------|-----------
Value 1  | SubValue 1
        | SubValue 2
---------|-----------
Value 2  | SubValue 3
        | SubValue 4
        | SubValue 5

This does not work:

   <tr:table value="#{fichaOperadorBean.attributes}" var="attribute">
       <tr:column>
           <tr:outputText value="#{attribute.xnomatrb}"/>
       </tr:column>
       <tr:column rendered="#{attribute.xtipdado eq 'S' or
attribute.xtipdado eq 'L'}">
           <tr:table value="#{attribute.attributeData}"
var="attributeData">
               <tr:column>
                   <tr:outputText value="#{attributeData.xvalor}" />
               </tr:column>
           </tr:table>
       </tr:column>
   </tr:table>


Whereas this does indeed work (the same, but using h:dataTable instead of
tr:table):

   <h:dataTable value="#{fichaOperadorBean.attributes}" var="attribute">
       <h:column>
           <tr:outputText value="#{attribute.xnomatrb}"/>
       </h:column>
       <h:column rendered="#{attribute.xtipdado eq 'S' or
attribute.xtipdado eq 'L'}">
           <h:dataTable value="#{attribute.attributeData}"
var="attributeData">
               <h:column>
                   <tr:outputText value="#{attributeData.xvalor}" />
               </h:column>
           </h:dataTable>
       </h:column>
   </h:dataTable>

Is there another intended way to use tr:table for this to work?
