Highlighting rows in rich:dataTable based on the row content

[linuxtuxie.j_007_b.live.com]

Hi all,

I am able to highlight certain rows in a rich:dataTable based on the row content by making use of the rowClasses tag by generating the value for the rowClasses tag.

However, if I add a rich:datascroller to the dataTable and use the sorting stuff, things break :)

The rowClasses value is not updated when I sort one of the columns....so in short, I do not get feedback from the rich:dataTable.
Is there a way to know which row is where in the rich:dataTable ?

or is there another and/or better method to accomplish this?

I solved my own problem by implementing the following code:

Instead of generating the rowClasses attribute for the rich:dataTable tag, I generate the value for the styleClass attribute on the rich:column tag for each row. Each time the dataTable gets rerendered (due to filtering or sorting) it calls the getColor method for each cell

example:

<rich:dataTable id="itemData" var="item" value="#{items}" reRender="ds" rendered="#{items.rowCount!=0}">
   <rich:column styleClass="#{item.color}" sortBy="#{item.name}" filterBy="#{item.name}" filterEvent="onkeyup">
      <f:facet name="header">Name</f:facet>
      <h:outputText value="#{item.name}" />
   </rich:column>

   <rich:column styleClass="#{item.color}" sortBy="#{item.value}" filterBy="#{item.value}" filterEvent="onkeyup">
      <f:facet name="header">Value</f:facet>
      <h:outputText value="#{item.value}" />
   </rich:column>

   ...
   ...

   <f:facet name="footer">
      <rich:datascroller id="ds" renderIfSinglePage="true"/>
   </f:facet>
</rich:dataTable>

And here item.color contains the texts greenRow;redRow;... which on its turn is defined in the stylesheet
