This is a frequent gotcha. Your best bet is to look through the archive,
because I don't remember the current details. My answer is always that
this is an action (because of the Exported attribute, yes ?) and actions
belong in the model class, not the controller. Then IIRC, Aaron points
out that you can now put it in the controller if you want and somebody
else will point out that it's to do with compile-time versus run-time
which is documented in the cookbook.
Or something like that. It's too late for a better answer. The important
thing is the knowledge that the answer is in the archive of this list.
