We are unable to get a legend-only requests to work with the latest version of MapViewer (10.1.3.1). The problem seems to be that the inclusion of a <box> bounds element causes MapViewer to assume that a map is being requested, not just a legend. Further, there doesn't seem to be a way to force the MapViewer Bean to dispose of its current bounds, so once a MapViewer bean has its bounds specified, all future requests generated from that instance will have bounds.
Below is a standalone MapViewer legend request, including the <box> element. For us, this request brings back some random geometry (perhaps left over from an old request?). If the <box> element is removed, the legend returns as expected.
Any suggestions on a way to work around this?
Thanks,
