Fred,
I'll look for "changed".
I can re-create the error in the console - please see below. The error
would suggest that attribute_names in attributes_with_quotes is set to
true though as you can see the 'attributes.keys' for the instance
being saved seems ok.
*** CONSOLE OUTPUT - r, an existing Root object in the DB, raises an
error when I try to save it back
r = Property.find(1)
