[Chameleon] Unknown error with msProcessAutoProjection

[Paul Spencer]

Ivan,

Chameleon generally expects you to have a projection defined in your  
map file.  This is somewhat unnecessary in the most general case, but  
many of the widgets rely on a projection being set even if they don't  
really need it, and the exception code to handle no project has not  
been written.  Please add an appropriate projection ... and  
unfortunately I am not a PROJ expert so I can't help you there :( ...  
but if you ask on the mapserver-users list with your parameters  
below, someone will jump in, I am sure!

Cheers

Paul

PS if the problems persist after setting a projection, please get  
back to this list ...
