doubled warning that file is emprt

Hi,

I am new to Yii and I am working on the form where file has to be uploaded.

I am using validation rules:

array(‘fileName’, ‘required’),

array(‘fileName’, ‘file’, ‘types’=>‘pdf, png’),

It works fine, but when file is empty, I see warning "File Name cannot be blank." twice

I could remove first restriction, but than I am loosing red astrix, indicating that this field is mandatory.

Any tips?

Thanks

Jerzy

array('fileName', 'file', 'types'=>'pdf, png', 'allowEmpty' => true),

or

array('fileName', 'file', 'types'=>'pdf, png', 'skipOnError' => true),

Thanks!
