I'm not familiar with that exact error but if that pageValidate
method is in your Login page (or it's superclass, etc.), then you're
creating a sort of recursive condition where activating the Login
page when the user is not logged in will redirect back to the Login
page.
The Vlib app uses @Meta annotations to specifically mark the Login
page as "anonymous" and the pageValidate() method is supposed to
allow access in that case rather than redirect.
The above may be way off base since I can't see your superclass or
more of your code...

Hi,
I'm trying to implement a login page using VLib's mechanism so I
implemented
PageValidationListener in my page's superclass with the following:
public void pageValidate(PageEvent event) {
if (!isUserLoggedIn()) {
LoginPage login = getLoginPage();
login.setCallback(new PageCallback(this));
throw new PageRedirectException(login);
}
}
Very simple. Actually looks just like the VLib example, however I'm
getting
the following exception before I get to the login page:
A validate cycle during page activation was detected: LoginPage;
LoginPage.
Anyone knows what it means and how to fix it?
I even tried using the PageBeginRenderListener instead but what
happens is
the PageRedirectException actually gets thrown! It's not caught by
tapestry
and the page is not redirected. Any ideas?
Thanks
Denis
