Subject: Re: How to get the Component inside advice?

Chances are your instanceof is failing because you put the SecurePage
interface into the pages or components package; move it up a level, to
a non-controlled package, so that the services layer and the component
layer can agree.  Anything inside the pages or components packages (or
mixins or base) will be loaded by a different class loader, and this
causes these apparently anomalous ClassCastExceptions.

But Thiago is right, Tapestry has a proper place for this kind of
thing, if you check my blog, you'll see an article where I head down
the same path as you (I've recently done this kind of thing for a
couple of different clients). I hope to have a simple authentication
framework, possibly as a Tapestry extension, at some point in the next
couple of months.
