[Chameleon] Querying a dynamic layer

[Paul Spencer]

Ken-ichi ...

actually I'm not sure that I have actually seen this done ... anyone 
else done this and got it to work?

Have you compared the layer definition that is generated by your script 
to the one you added to the map file?  Perhaps there is some subtle 
difference?

Cheers,

Paul
