remapping

[eluser]tzi0[/eluser]
Hi all
i have a _remap() function in my Admin controller:

Code:

function _remap($method)
    {
        if ($this->session->userdata("user_id"))
        {
            $this->$method();
        } else  
        {
            $this->index();
        }
    }

ok. now, if user requested a method with parameter, parameter doesnt pass:

Code:

function editcontent($id="none")
    {
        echo $id;
        if (is_numeric($id))
        { ... }
                ...
        }

$id always is "none". Why that? Have i to write something else in my _remap() function?
