    What does a4j:actionparam do in tooltip with datatable?

    Ziyang Zhang Newbie

      In the source of this tool tip example:

      http://livedemo.exadel.com/richfaces-demo/richfaces/toolTip.jsf?tab=table&cid=166644

      We can see rowKeyVar is assigned in the following line.

              <rich:dataTable value="#{toolTipData.vehicles}" width="400"
                  var="vehicle" rowKeyVar="row">

      And it is used in the following line:

                              <a4j:actionparam name="key" value="#{row}"
                                  assignTo="#{toolTipData.currentVehicleIndex}" />

      What does this code do?????

      Thanks a lot.
