Found a solution: As far as I can tell, the validation methods expect the data all to be in (for example) $this->data['Question']['FunctionalArea'].
(See line 2196 of model.php, where the only data considered for validation is in $this->data['Question'].) But the save method expects all the data to be in $this->data ['FunctionalArea']['FunctionalArea']. (See lines 1120-1125 of model.php, which considers everything in $this- >data, including HABTM relationships.) So I my View posts the data to $this->data['FunctionalArea'] ['FunctionalArea'], and in the Controller I copy it to $this->data ['Question']['FunctionalArea'], so that both validation and saving work.
