Subject: [mapguide-internals] Patch for ticket 2548 (Selection not cleared server-side)

Hi All,

I've attached a patch for ticket 2548

http://trac.osgeo.org/mapguide/ticket/2548

When the fix for ticket 2464 (http://trac.osgeo.org/mapguide/ticket/2464)
was made, the case for clearing a selection was not properly handled. This exists as a call to QUERYMAPFEATURES with an empty FEATUREFILTER and no GEOMETRY specified. 

The existing RenderForSelection method throws an argument exception on this particular condition (empty feature filter and null geometry). This patch changes the check to return from the method immediately.

The net result of this patch is that it allows for the QUERYMAPFEATURES operation in the mapagent to properly clear selections by omitting the GEOMETRY and FEATUREFILTER parameters.

Please review. Thanks.

- Jackie
