Many thanks to all who replied. I went with a version of David
Leangen's code modified for my own use with Wicket 1.3 as follows.
It's working great.
Thanks again,
Justin

Subject: Given a Page subclass and its PageParameters, how to
determine the URL string?
Hi,
(I've poked around the Wicket mailing list archives and FAQ and
haven't seen an obvious solution for this.)
My question:
How do I to determine in advance what the encrypted URL string of a
page (plus its parameters) will be? In case it matters, I'm using
CryptedUrlWebRequestCodingStrategy.
The reason for the question:
I've created a rudimentary "VerifyEmailPage" in my app that takes an
email address as a page parameter. A URL string will be put in an
email message and sent to a user when that user creates an account.
(The URL string accesses the VerifyEmailPage.) The user then clicks
on the URL in the email in order to validate the email address. I
need a way to determine what that URL should be (so I can send the
URL to them).
Thanks for any info,
Justin
