<p class=MsoNormal style='margin-bottom:12.0pt'>I have no idea how to do this
in fusion, but you will likely have to run through the layer list when doing a
"layer.show()".<br>
I think there is a call that updates the map without returning the image. You
can use that, but it will require multiple server calls over http.<br>
