SerializationTypeMismatch in Production Mode
In production mode, I keep getting this error the 2nd time it loads a
page with a serialized attribute:
ActiveRecord::SerializationTypeMismatch (answers_container was

`unserialize_attribute''

The controller code is:

ActiveRecord attributes -- strange behavior when adding Array to an element
Hi,
I have a database table and associated ActiveRecord model. I was
trying to store (temporarily) an array in one of the attribute
elements - not to save it, but just so that I can keep some form data
in a sensible place. A stripped down version of the problem I''m having
