Mike, thanks for the example.
I tried it but I'm seeing these results...
When I put the mouse over a column that has a popup tag,
a small empty component (with tiny scrollbars) appears next to
the mouse, and the text associated with the popup appears
separately to the right of the mouse, overlaying the text in another
column. The text has no border, maybe just spaces around it.
The text and tiny scrollable field do move with the mouse.
Have you seen/heard of this behavior?
The text must belong in the empty component, but how does it get there?
And does the popup field *have* to have scrollbars? It ought to be
just a box.
Thanks again for your help.
Tom

Here's an example of displaying the first value in a list for a
column, and then using t:popup to display an entire list of values on
hover. jstl:length() is only available if you're using facelets,
though. I've manually edited this page code to provide a simpler
example, so hopefully I didn't introduce a typo.
<t:column>
<f:facet name="header">
<h:outputText value="Name"/>
</f:facet>
<h:outputText
rendered="#{(itemList != null) and (0 != jstl:length(itemList))}"
value="#{itemList[0].name}" />
<t:popup id="namePopup"
rendered="#{1 lt jstl:length(itemList)}"
styleClass="popup"
closePopupOnExitingElement="true"
closePopupOnExitingPopup="true"
displayAtDistanceX
="10"
displayAtDistanceY
="10" >
<h:outputText
style="color: green;"
value=" [#{jstl:length(itemList)}]" />
<f:facet name="popup">
<h:panelGroup>
<t:dataList
value="#{itemList}"
var="item">
<h:outputText value="#{item.name}" />
<t:htmlTag value="br" />
</t:dataList>
</h:panelGroup>
</f:facet>
</t:popup>
</t:column>
