Page redirecting on client side
I thought throwing a PageRedirectException() will cause a client-side
redirect. Is that true? I'm not seeing that. If not, how do I do a
client-side URL to a valid Tapestry page using the target page's name?
Thanks

Thanks - should be simple to introduce a helper method into my page base
class. I tried using the ExternalPage service, but then I'd be forced to
make everything an external class. This is a better solution. I didn't want
my entire application to refer to the login URL!!!

Throwing PageRedirectException sure seems to be throwing a lot of
confusion...
PageRedirectException is caught in AbstractEngine.service(). When
caught, it performs a requestCycle.activate() on the specified page,
discards any existing output, and then renders that page.
To perform a client-side redirect, you need to throw a
RedirectException. Since RedirectException is constructed with a full
URL, you'll need to generate the appropriate Tapestry URL manually.
e.g. To perform a redirect to a page:
String page = // Page to which I'd like to redirect
String url =
requestCycle.getEngine().getService(Tapestry.PAGE_SERVICE).getLink(requestCycle,
requestCycle.getPage(), new String[] { page }).getURL();
throw new RedirectException(url);
This is an area that I hope to streamline in 3.1.

PageRedirectException just activates a new page internally within the
current request cycle.
Try throwing a RedirectException instead. Pass a url that starts with
"/" or contains "://" to generate a temporary redirect (3xx) response to
the browser.
You can generate the url using PageService.getLink() method.
For Example:
Object[] parameters = {"MyPage"};
throw new RedirectException(engine.getService("page").getLink(cycle,
this, parameters).getAbsoluteURL());
Cheers,
Jon
