How to load a view for the error page?

[eluser]Aquillyne[/eluser]
Well I've been fiddling around trying to store the error message in flashdata from the Session class.

I figure trying to use the Session class in the MY_Exceptions class is too early. Is there a way of doing this?

EDIT:

I've been trying the following:

Code:

function _redirect($error)
{
    if (isset($this->session->userdata("error")))
    {
    ...

And this is returning a fatal error: "Can't use method return value in write context." What's wrong with that bit of code?
