</div>

the full text of the error is below. It seems like that Rails gets  
confused with dependencies. i tried the solution offered online,  
specifically

insert

config.load\_paths += %W( #{RAILS\_ROOT}/lib )  
config.load\_once\_paths += %W( #{RAILS\_ROOT}/lib )

in config/development.rb

but it didn’t work. every works on the first attempt (i need to create a  
new form and then save it to the database), but when it fails on the  
second attempt. so if i the same user creates a second form and tried to  
save it, it doesn’t work.

does anyone know what the problem might be?
