would the following be possible: I would like to have another bean pull the data for a tooltip whenever the user mouses over an item. Is this possible or is the tooltip only populated when the dataTable is being populated?

<rich:dataTable value="#{toolTipData.vehicles}" width="400" var="vehicle" rowKeyVar="row">
 <rich:column>
 <f:facet name="header">
 <h:outputText value="##"/>
 </f:facet>
 <h:outputText value="#{row+1}" />
 </rich:column>
 <rich:column>
 <f:facet name="header">
 <h:outputText value="Make"/>
 </f:facet>
 <h:outputText id="make" value="#{vehicle.make}" >
 <rich:toolTip direction="top-right" mode="ajax" delay="30" styleClass="tooltip" immediate="true" layout="block">
 <a4j:actionparam name="key" value="#{row}" assignTo="#{alternateBean.currentVehicleIndex}" />

 <h:panelGrid columns="4">
 <f:facet name="header">
 <h:outputText value="Vehicle details:" />
 </f:facet>
 <h:outputText value="make:" />
 <h:outputText value="#{alternateBean.make}" styleClass="tooltipData" />
 <h:outputText value="model:" />
 <h:outputText value="#{alternateBean.model}" styleClass="tooltipData" />
 <h:outputText value="year:" />
 <h:outputText value="#{alternateBean.year}" styleClass="tooltipData" />
 <h:outputText value="milage:" />
 <h:outputText value="#{alternateBean.milage}" styleClass="tooltipData" />
 <h:outputText value="zip:" />
 <h:outputText value="#{alternateBean.zip}" styleClass="tooltipData" />
 <h:outputText value="listed:" />
 <h:outputText value="#{alternateBean.listed}" styleClass="tooltipData" >
 <f:convertDateTime dateStyle="short"/>
 </h:outputText>
 <f:facet name="footer">
 <h:panelGroup>
 <h:outputText value="vin: " />
 <h:outputText value="#{alternateBean.vin}" styleClass="tooltipData" />
 </h:panelGroup>
 </f:facet>

 </h:panelGrid>
 </rich:toolTip>
 </h:outputText>
 </rich:column>
 <rich:column>
 <f:facet name="header">
 <h:outputText value="Model"/>
 </f:facet>
 <h:outputText value="#{vehicle.model}" />
 </rich:column>
 <rich:column>
 <f:facet name="header">
 <h:outputText value="Year"/>
 </f:facet>
 <h:outputText value="#{vehicle.year}" />
 </rich:column>
