I'm struggling through this one, but it's beating me down more so than usual.
This is the error message I'm getting: Assigned relationships must be an array or null, given relationship value for layout is invalid. The part that is causing the error:

$page = new Model_Page();
$page->layout = Model_Layout::find(\Input::post('page_layout'));
$page->title = \Input::post('page_title');
$page->type = 'page';

My many-to-many properties:

    protected static $_many_many = array(
        'layout' => array(
            'key_from' => 'id',
            'key_through_from' => 'page_id',
            'table_through' => 'pages_layouts',
            'key_through_to' => 'layout_id',
            'models_to' => 'Website\Model_Layout',
            'key_to' => 'id',
            'cascade_save' => true,
            'cascade_delete' => false,
        )
    );

Can anyone point me in the right direction.
