Hello, I am trying to create in the main Layout of the application fields of selection of fields of the model, and other to insert its value.

(Colinux is really amazing cause it lets you run actual linux binaries und Windows.) So here is my problem, which by the way exists since Rails 0.5.0 I think. It was the reason I tried Colinux in the first place, cause the error first

Hi, I have a strange problem that only occurs on the production server. I''ve been banging my head for hours trying to figure it out with no success.
