Validation pronlem with standard upload script and forms

[eluser]wizzer[/eluser]
I have a form and on it I have an upload script which is taken from Ci documentation. When my form is submitted without a file none of my fields are repopulated, none of the error for the other form fields appear, it only says I have forgot to add a document.


This line

Code:

$data['error'] = array('error'=>$this->upload->display_errors());

seems to interfering with

Code:

$this->form_validation->run()

I dont know what to do, any help would be appreciated.
