you said it yourself:
"Insure that the component identifier names match
the appropriate property names."
what that says is that the model you get is the property of the model
object that is in the cpm with the name of component id.
so since your links id is "foo" it will try to pull out the model
object from the cpm and call getfoo() on it, the result of which is
the model object of the link
