[fw-general] Zend_Form Int filter

[umpirsky]

Hi.

I have several fields of int type which I have in my form. I want to get
integer when I get values from form after submission. So, I attached int
filter like:

->addElement(
                        'text',
                        'name',
                        array(
                                'label' => 'Lab:',
                                'filters' => array('Int'),
                                'required' => true
                        )

This works ok, but when I render empty form, I get zero in my input, which
looks very odd. I want empty field when nothing entered. Should I use new
Zend_Filter_Null in combination with int filter, or there is sth else I can
do?

Regards,
Saša Stamenković.
