[UMN_MAPSERVER-USERS] RE : [UMN_MAPSERVER-USERS] Problems displaying PostGIS Layer

[Skweda O'Bomsawin]

Obviously, this question is for Bill (or maybe William, I don't exactly know
his name).  By the way Bill or William, could you please give us a sign of
life and help to resolve these misunderstanding (and maybe provide us with
some of your Python script)?

Tyler, I agree with you, you don't have to set the layer status to ON or
DEFAULT if you do that in your script (Swing or PHP).

PostGIS Layer

Skweda,
Regardless of the status of the layer, you're obviously turning it on in
your 
script or it wouldn't give an error.  Can you provide us the script as well 
so we can see what you are doing with it?  Are you modifying anything about 
this layer?
