Ryan, good point about the error message being displayed for any
error. I hadn't thought that far ahead. The solution would be to
specify the keyname of the validation rule. The example in the manual
not fixed for this situation is: $this->Form->input('Model.field',
array('error' => array('tooShort' => __('This is not long enough',
true) )));
As for the second point about handling this in the controller. It's
the manual itself that says this should be handled with FormHelper.
>From this page here: http://book.cakephp.org/view/1143/Data-Validation
, it says: "For more information about how to handle the displaying of
validation errors, check out the section covering FormHelper."
