I'm trying to constrain two bones to follow a null in an action window, with an "Aim At" constraint, for controlling eye direction of a model. All of which works fine and well.
However when the model containing this setup is opened in a Chor this constraint no longer works. How should I be doing this?

Did you do this in a pose? Is the pose turned on in the Choreography?
Are there any other nulls in the chor? If you have multiple Null1's... there will be a mixup.
I usually make this constraint a part of the model... in the model's bones mode make a new null -placed in front of the character at eye level- and drag it to the top of the bones list (child of nothing) RENAME IT something like 'eyes aim at NULL'... Then make a new pose (on/off) and add the aim-at constraint. Now you can turn that on in an action,pose or chor and animate the null. You can also give the eye-bones a euler constraint (in that same pose) to eliminate 'roll-back' effect if the null goes behind the head- for example.

Yes, that got it! Just what I needed to know
Thanks a lot!
