Hello I'm developing a Web Application using RichFaces 3. I have a rich:dataTable with individual rich:column. One of these columns has a Date value and there is this requirement where if the date is the same on consecutive rows the value has to be shown only on the first row, subsequent rows with same value will show nothing. So I need to save the date value for comparison on subsequent rows. Does anybody know how to do this with richFaces?

Well, there's a brute force which works: call a method of a bean (which I assume you have) which will tell if you need the date (alternatively, what to display). Something like:
<rich:dataTable value="#{yourBean.items}" var="item">
...
<rich:column>
<h:outputText value="#{item.date}" rendered="#{yourBean.isDateNeeded(item.date)}"/>
</rich:column>
...
</rich:dataTable>
And in the bean just keep a list of dates which were already shown or alike.
P.S.: There's actually number of ways to achieve the goal even without rich faces, js function for example.
