Asunto: Re: Wicket page HTML extractor
Yes, I've used code from mail example, as I said. The mail example does not
fit into my needs because the rendering thread must be independent,
out-of-request. ( for example into a Timer/TimerTask)
I've been looking into Wicket tester classes
(http://wicket.apache.org/apidocs/1.5/org/apache/wicket/util/tester/BaseWicketTester.html)
and I've made changes to code.
Luckily, I've succeed and I got a functional request-independent page
renderer, which only dependes on webapp and it's easy to use:
MyAppPageBuffer.java

If you want to see and review it, comments are welcome

Pd. with a little side effect, but I'll talk about it on another mail

Hi,
Why don't use the source of MailTemplate example
(http://www.wicket-library.com/wicket-examples/mailtemplate) ?
Your code seems to be much more complex.
