[mapguide-users] Map Layers Transferring Between Users

[Paul Spencer]

Hi pD,

it sounds as if you are modifying something in the Library:// rather  
than making a copy in the Session:// and modifying it there (either  
your Layer or FeatureSource I'd guess).  Perhaps you could describe  
what the code does (in general terms) and we might be able to point  
out where you should be using the Session instead.

Cheers

Paul
