save - Symfony 1.4 Validation Error Unsigned -


when try save form in symfony 1.4 gives me these errors:

validation failed in class cmscontentelementfile 4 fields had validation errors:  * 1 validator failed on title (unsigned) * 1 validator failed on alt (unsigned) * 1 validator failed on link (unsigned) * 2 validators failed on direction (length, unsigned)

what errors mean?

edit:

validators form fields: 

   $this->setvalidators(array(               'title'      => new sfvalidatorstring(),               'alt'        => new sfvalidatorstring(),               'link'       => new sfvalidatorstring(),               'width'      => new sfvalidatorinteger(),               'height'     => new sfvalidatorinteger(),               'direction'  => new sfvalidatorpass()           ));

it works now. problem give field "direction" param "unsigned:1 , varchar. fix problem. hope helps somebody.
