Kohana 3.2 auth module and fatal error
===

it just not serious question.
but I found something in kohana 3.2 (and I not understand)

so, I already implement authorization with Auth module 
and alway check authorization with this code.

    //in controller
        if(Auth::instance()->get_user() == null)// not login
        {
             $this->request->redirect("authen/login"); //navigate to login page
        }

it working fine !!

then I try to put this code in view file. (anywhere in view file)

    <?php $dummy->dummy()?>

So, this code  will make error like this

    Fatal error: Call to a member function dummy() on a non-object

it look like a normal case, because $dummy is not defined


then I refresh it or navigate to other page

    Auth::instance()->get_user() == null // it become true, after fatal error happen !! and redirect me to login page


My Question is 
 - **Why 'Auth::instance()->get_user()' is return null    after fatal error happen**?


Anyone share this?
