By intval:

this removes it from required list, which means it can be removed from the _POST array.
While in fact I still want it to be required and present in the post array, but also allow it's length be zero.
Should be something like this:

`
return array(

array('subject, bb_text', 'required'),

array('subject', 'length', 'max'=>255, 'min'=>5),

array('bb_text', 'length', 'min'=>5, 'allowEmpty' => true)

);
`
