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>

I have a list that is populated from a dataTable.
data in several columns (outputText) is truncated by the backing bean
to help keep the overall list within an area.
I'd like to display the full data in a column when the user moves the mouse
over a column with truncated data.
I've been looking at onmouseover and t:popup but don't have a clue
on how these could be used to display the full data.
Can anyone offer a piece of code or a reference to some code that does
this?
Thanks for your help
