Hi Howard, I have found both ApplicationInitializer and ComponentSource only
available by injection within a page which is already instantiated. What I
was looking for is a way to create all pages (or even just one) before a
user request would hit.
Also, could you give just a little bit more detail about what you mean with
"perform a little bit of cleanup work"? What will it take for Tapestry to
make pages return to the pool and stay available until undeploy time? This
would also enable us to create a number of page objects per page and have
them pooled and ready for hits. Especially if a minimum of them aren't
garbage collected later.
For now, I would be more than happy with a semi-proper workaround. If write
something decent, I'll try to contribute it somewhere.
