Hi!
I'm working on a security package for Tapestry (to be open-sourced soon)
and I'm following the typical Dispatcher-based approach. Now I need to
check if the requested page has a given annotation and read its values.
This already works. I also want my dispatcher to get the annotation
presence and values when a page class is live reloaded.
I'm using ComponentClassResolver to map page names (user/edit) to their
page classes names, get the Class instance and then get the annotation
values. But, without an application restart, my dispatcher doesn't see the
new annotation values. I could use ComponentSource.getPage(), but it
checks out a page instance from the pool and invokes Page.attached(). I
suspect this hurt perfomance, as the page checkout would be too heavy to
be executed twice per request (one in the security dispatcher, other to
process the page render/event itself).
Any suggestions? Am I right in the assumption that using
PageCache.checkout() to do security checks would hurt performance?
