Code

public function init_display($reset = FALSE) {

        // displays, but the clone is pretty shallow and doesn't necessarily
        // clone the displays. We can tell this by looking to see if a handler
        // has already been set; if it has, but $this->current_display is not
        // set, then something is dreadfully wrong.

            // is. Make sure of it.
