[OpenLayers-Users] Sort of Feature switcher

[darrepac]

Arnd

I have a strange things:
With your online example, everything works ok but with my local version I
got "error" text every time I check one radio button...So I cannot select
from the list, the feature I want (always got "error") but the rest works
ok.

Any clue of where it could come from? I am with FF
