Description
In a subclass of a form, I have the following code:
$this->addElement('text', 'from', array(
'label' => 'From',
'required' => true,
'validators' => array('digits', array('greaterThan', false, 0)),
'size' => 15,
));
$this->addElement('text', 'to', array(
'label' => 'To',
'required' => true,
'validators' => array('digits', array('greaterThan', false, 1)),
'size' => 15,
));
This leads to the following warnings:
Warning: Missing argument 1 for Zend_Validate_GreaterThan::__construct(), called in D:\Projects\...\...\library\Zend\Form\Element.php on line 2000 and defined in D:\Projects\...\...\library\Zend\Validate\GreaterThan.php on line 68

This obviously has to do with PHP treating 0 as empty().
I guess that other validators, at least lessThan, but others probably as well, also suffer from this bug.
The GreaterThan validator has no problems with "0".
Even unittests exist for testing this value.
As there is wether an empty() nor an other method call within the GreaterThan validator, I expect that the main problem is within Zend_Form, and not Zend_validate_GreaterThan.
Also the given failure message let me expect this.
A not given parameter, as returned within the php exception, is not a case which could be handled by the class itself.
