Fetching the rendered page result.

[Olivier Jacquet <oj...@jax.be>]

Hello,


Is it possible to access the rendered page result from within a page 
without calling the actual http:// address?

I would need this so that I can setup a page that generates xml (xsl-fo) 
to be processed by fop [1] to convert it to pdf. That is much more 
readable than generating the xml of pdf programmatically.

So, basically, what I want is the following unless someone knows a 
better way:

class MyPage {
   function onSubmit() {
      FOPPage xml = new FOPPage();
      String output = xml.render(); // or something like this
      ...save the output to disk...
      ...convert the output to pdf on disk...
      ...send the generated pdf to the user...
   }
}

MyPage.tml:
Click the button to get the pdf:
<t:form><input type="submit"></t:form>

FOPPage.tml:
<?xml version="1.0" encoding="iso-8859-1" ?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
...


Regards,
Olivier

This is tricky, but doable.  You have to jump into a bit of the
internals to pull it off, however.

Really, Tapestry should add a service to assist in this, something
where you feed in a page instance or page name and get back a
Document.  Add an issue to JIRA.
