Controller, Model, View and Helper all have a class variable called
'validationErrors';
When Model::invalidFields() is called (e.g. from Model::save()), the
model's $validationErrors is set.
This array is field-keyed, like `array( 'title' => ..., 'description'
=> ...)
When the controller goes to render, it constructs the view and then
(for each model it knows) passes that model's
$validationErrors to the View in a modelname-keyed array, so $View-
>validationErrors looks like
array(
'Ham' => array('title' => ..., 'description' => ...),
'Eggs' => array('foo' => ..., 'bar' => ...)
)
Then the View passes this array on to each of the helpers it loads.
So, from within the Behavior, the only object you have access to is
the parent model. You cannot directly influence the view (it doesn't
exist yet) or the controller (that would be terrible MVC).
Your best bet would be to set the model's validationErrors array, with
a prefixed key (like $Model->invalidate('attachment_' . $fieldName,
'...'). This will then get propagated to the view and then the
helpers.
You'd then be able to access this directly in the view by using $form-
>error('Model.attachment_whatever');
