code igniter : Weird problem : problem just in chrome : works fine in IE and Moz

[eluser]technology.guy[/eluser]
I have a function as below in controller_a

Code:

function abc()
        {
            $this->load->model('model_a');
            $query = $this->model_b->get_data();
            
            if($query)
            {
    
                 $data = array(
                                'a'  => true,
                                'b'  => $query->b,
                                'c'     => $query->c,
                              );
                  
                $this->session->set_userdata($data);
                redirect('controller_a/view_a'); // simply calls a function that loads view_a
            }

The problem is that in view_a

<?php echo $this->session->userdata('a'); works fine for b also works fine but for c it doesnt show anything.

Also I tried echoing $query->c int the controller before setting the data works fine but cant access it in the view .... dont know what is the problem

Any help will be appreciated
Thanks
