[JSF 1.2] conditions for table rows inside dataTable tag

Hi all,

question - is it possible to somehow manage table row items or even whole
table row inside dataTable tag:

what I want to get in result:

<h:dataTable var="raw">
   <h:column>
       <c:choose>
            <c:when test="condition1">
                   1
             </c:when>
            <c:otherwise>
                  2
             </c:otherwise>
       </c:choose>
   <h:column>
</h:dataTable>

I tried this, but it doesnt work and I suppose why. So is it possible
somehow to work with dataTable items in any way?

Thanks,
Anton

I don't know what happened in your case (why rendered="#{1==2}" 
evaluated to "true"), the "rendered" attribute accepts any boolean 
expression, take a look in this article to see the sintax and operators 
accepted by the EL:

Thanks,

wanted something more 'dynamic'

by the way which conditions accepts rendered attribute?
I tried rendered="#{1==2}"
and component is still being rendered - maybe I made mistake in expression?

Try this:

<h:dataTable var="raw">
   <h:column>
     <h:outputText value="1" rendered="#{condition1}" />
     <h:outputText value="2" rendered="#{not condition1}" />
   <h:column>
</h:dataTable>

Doesn't EL checks give you what you need. like rendered="condition" for
components to be rendered in that column for that condition.
