X Y Mouse Click Coordinates in the Request Map?

Question

I have a mapping application that layers several images with a clickable top layer. When I wrap the top image in a command link I don't get the x and y coordinates of the mouse click in the request map. So I've had to use a regular command button with an image property. This works fine but doesn't allow me to use partial page rendering to limit the refresh of particular images in the stack. Can the x,y coordinate of the mouse click be returned with straight ADF?
(I"ve included the code for retreiving the x and y coordinates under the jspx code)
<af:panelGroup type="vertical">
<af:objectImage source="#{backing_collect2.activeSource}"/>
<af:objectImage source="#{backing_collect2.baseSource}"
inlineStyle="position:absolute;left:0px;top:0px"
binding="#{backing_collect2.baseImage}"/>
<af:objectImage source="#{backing_collect2.allPointSource}"
inlineStyle="position:absolute;left:0px;top:0px"
binding="#{backing_collect2.allPointImage}"/>
<af:objectImage source="#{backing_collect2.userPointSource}"
inlineStyle="position:absolute;left:0px;top:0px"
binding="#{backing_collect2.userPointImage}"/>
<af:objectImage source="#{backing_collect2.activePointSource}"
inlineStyle="position:absolute;left:0px;top:0px"
binding="#{backing_collect2.activePointImage}"/>
This following fails to return x and y in the request Map, imageMapType="server"
attr on objectImage does not help
<af:commandLink actionListener="#{backing_collect2.processClick}"
action="#{backing_collect2.collectAction}"
inlineStyle="position:absolute;left:0px;top:0px">
<af:objectImage source="#{backing_collect2.activeSource}"
inlineStyle="position:absolute;left:0px;top:0px"/>
</af:commandLink>
I have to use the following regular command button to get x, y click coordinates in the request map. But using this component makes its impossible to use partial page rendering to limit refreshes of the images above.
<h:commandButton image="#{backing_collect2.activeSource}"
binding="#{backing_collect2.activeLayer}"
actionListener="#{backing_collect2.processClick}"
action="#{backing_collect2.collectAction}"
style="position:absolute;left:0px;top:0px"/>
</af:panelGroup>
// Code to get x and y from the request map
visit.setLastClickPoint(visit.getClickPoint());
FacesContext fc = FacesContext.getCurrentInstance();
String clientId = actionEvent.getComponent().getClientId(fc);
java.util.Map requestParams = fc.getExternalContext().getRequestParameterMap();
String xString =(String) requestParams.get((String)clientId + ".x");
String yString =(String) requestParams.get((String)clientId + ".y");
int xMouse = (new Integer(xString)).intValue();
int yMouse = (new Integer(yString)).intValue();
