AR Callbacks not called

I have an AR model with a has_one association.

AFAICT, using a straightforward logger that works everywhere else, callbacks on on the associated model never get called.

I've put logger lines in the parent model and in the child model for before/after_update and before/after_validation_on_update.

I get log lines for the parent, and none for the child. The child relationship is working--form params data is being saved to the child data table just fine, but none of the actions in any of the callbacks for the child are working.

Is this normal??

Hmm. Nevermind. I made a simple change in some controller code, and now callbacks work. Puzzling (considering the save was working), but apparently an app-level problem.
