Both forms below yield an invalid view exception when the DbView->render is returned to the caller.

public function build()
{
    $this->subject( $this->communique->template->subject );
    return DbView::make($this->communique->template,
        $this->context, [], 'body' )
        ->render();

/* return DbView::make( $this->communique->template )
->field( 'body' )
->with( $this->context )
->render();
*/
}
