So far so good. . . .
>> c.batch_id="375a4e3c-5fc1-11df-94f7-00065b3f562c"
=> "375a4e3c-5fc1-11df-94f7-00065b3f562c"

=> true
What? But .percentage isn't even defined yet . . .
>> c
=> #<Component
@values={:batch_id=>"375a4e3c-5fc1-11df-94f7-00065b3f562c",
:ingredient_id=>"4ace430c-2357-11df-9ce0-00065b3f562c"}>
>> c.percentage = 50
=> 50
>> c.valid?
=> true
>> c.ingredient_id = nil
=> nil
>> c.valid?
=> false
I cannot figure out why the validation system is correctly monitoring the two
_id parameters, but completely ignoring the percentage.
