Here is how I catch the 'row id' in my application:
<t:dataTable id="TheDataTable" var="data">
<h:column>
<f:facet name="header"><h:outputText value="Sequence #"/></f:facet>
<h:commandLink action="#{navigation.reload}">
<h:outputText value="#{data.sequenceNum}"/>
<t:updateActionListener property="#{bean.currentSequenceNum}"
value="#{data.sequenceNum}" />
</h:commandLink>
</h:column>
</t:dataTable>
This is generalized, stripped-down code - obviously I have other columns
and such. The user will see in the first column a list of numbers. If
they click a number, the <t:updateActionListener> will update the
property on the bean with the value they clicked (data.sequenceNum).
Then the <h:commandLink> tells navigation to reload the page. We use
somewhat odd navigation on our site, so don't get confused by that.
This works because
* I have a sequence number stored in each bean of the collection that
dataTable is displaying
* I can access that bean in the jsp by using the "var" attribute in
dataTable
If your data doesn't actually have a row id property, perhaps you should
add one.

Thanks Volker.
How do you catch the 'row id' though?

Hi Alex,
we do this by using h:commandlink, with parameter, for displaying
the row data.
But you need to hit the text when clicking on a row.
