Are you trying to use GwsQueryEngine code outside of MapGuide beyond the feature join functionality?
Looking at the history on these files suggest to me that the GwsQueryEngine originated from AutoCAD Map and only the minimal amount of .h/.cpp files needed for the feature join capability to work was brought across. It's the only plausible explanation to me for why something like GwsOperationHandler.h lacks a basic include guard, it must've been included in a special way for their AutoCAD Map product, but this header is never used in MapGuide, so it never triggered any compiler errors. If you are indeed trying to use GwsQueryEngine code beyond its intended purpose (feature joins) in MapGuide, I don't think we can even try to support that scenario. All we can do is take your suggestions at face value as long as it does not compromise the feature join functionality we need for MapGuide. - Jackie -- Sent from: http://osgeo-org.1560.x6.nabble.com/MapGuide-Users-f4182607.html _______________________________________________ mapguide-users mailing list mapguide-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapguide-users
