Zend Framework 1.7 to 1.8 Exception caught by form Method getMaxFileSize does not exist

What cause this error message "Exception caught by form Method getMaxFileSize does not exist" after switching from 1.7 version to 1.8 or more

update: Issue produced by code

        ->addElement('file', 'avatar', array(
              'required'    =>开发者_Python百科 false
            , 'label'       => 'Upload File:'
            , 'destination' => '/data/avatar'
            , 'filters'     => array()
            , 'validators'  => array(
                  array('Extension', false, 'jpg,png,gif')
                , array('Size', false, 102400)
                , array('Count', false, 1)
            )
            , 'decorators' => $this->groupElementDecorators
        ))

update2: group decorators is just an array

$groupElementDecorators = array( 'ViewHelper', 'FormElements', 'File', 'Errors');

According to this issue, you must be using the following.

'validators' => array(
array('Size', false, array('min' => '3', 'max' => '9'))
)
