event="onRowDblClick" and event="onRowClick" problem


I have a problem on onRowDblClick event. when double click is done on a row i got a exception with message concurrent call conversation.
I think the problem is that two onRowClick event are sent to the server.

can someone help me?


<rich:dataTable id="cars" var="item" value="#{carManager.cars}" rows="5" width="100%" >
<a4j:support event="onRowDblClick"
action="#{cardManager.getCar(item.id)}"
reRender="carPanel"/>
<a4j:support event="onRowClick"
action="#{cardManager.showCar(item)}"
reRender="showCarPanel" />
<f:facet name="header">
<rich:columnGroup>
<rich:column width="15%">
<h:outputText value="Car Id" />
</rich:column>
</f:facet>
<rich:columnGroup>
<rich:column>
<h:outputText value="#{car.id}" />
</rich:column>
</rich:columnGroup>
</rich:dataTable>

when I do double click I got one click event and then double click event.
When I do double click event I want do only action="#{cardManager.getCar(item.id)}" and show reRender="showCarPanel". How i can ignore one click event when i do double click?
