[mapguide-internals] Patch for ticket 2459 (v2.6 QUERYMAPFEATURES produces inconsistent results)

[Jackie Ng]

Hi All, 

I've attached a patch for ticket 2459

http://trac.osgeo.org/mapguide/ticket/2459

The decision to use the existing
MgRenderingService::QueryFeatureProperties() API for writing attributes for
selected features is turning out to be a flawed one. The implementation is
known to behave differently from QueryFeatures() in some cases (given the
same parameters) that result in an inconsistent v2.6 QUERYMAPFEATURES
response.

This attached patch forgoes the use of this API, instead opting to write the
feature attributes part of the QUERYMAPFEATURES XML response directly from
the MgSelection that is part of the MgFeatureInformation.

Please review. Thanks.

- Jackie
