Re: Is it possible to have a renderer do its rendering at the end of the document?

[Martin Marinschek <ma...@gmail.com>]

Short answer: no, not really. What I would do in your case is I would
create a new component, and put it before the closing of your </body>
(or even create a new component which renders the body for you). Then
the renderer can register the stuff it wants to render with this new
component...

Martin
