[mapguide-users] Zooming to extent of multiple selections

[Trevor Wekel]

Hi Jo,

You could try turning on the enhanced server error reporting in serverconfig.ini.  It may provide some function call parameters in the server trace.log.  http://trac.osgeo.org/mapguide/wiki/MapGuideRfc49.  Not all API methods return enhanced information but some do.

When you are retrieving the error message, GetDetails() should return any information that is available.

Serverconfig.ini
 [GeneralProperties]
LogsDetail = MappingService:3,FeatureService:3,RenderingService:3,ResourceService:0

Thanks,
Trevor

Hi Jason,

Yes- but all it was telling me was that the argument was null. No clue as to
which argument though! Is there another level of detail you can get out of
the error handling, like a more verbose message?

Thanks

Jo
