v2.rails is undefined

[bwlang]

When I loaded up a form with a regex validation it seems to work okay, but i see the above error in firebug.

I think somehow FormatWithValidator is instantiated before the v2.rails and v2.rails.params are instantiated.
I worked around it by changing the line to

self.data = %{
v2.rails = {}; v2.rails.params = {}; v2.rails.params['#{args.first}'] = #{data.inspect.gsub(/\A/, '^').gsub(/\z/, '$')};
}
which obviously sucks since it wipes out any existing values, but works okay for me since I only have one validator. I don't know how to fix this properly (maybe a call to some function that checks then instantiates or somehow force v2.rails.js to be interpreted before this instantiation.)
