IExternalPages are handled by the ExternalService. All engine services
can provide a link to a particular page. Assuming you're using
annotation (caveat...I'm typing this directly into the email, so no
guarantees that it works, but the concept is correct):
@InjectObject( "engine-service:external")
public abstract IEngineService getExternalService();
public void RedirectToExternalPage( IRequestCycle cycle, String
pageName, Object[] params
)
{
ExternalServiceParameter esp =
new ExternalServiceParameter(pageName, params);
String url = getExternalService.getLink( cycle, false, esp
).getURL();
throw new RedirectCallback( url );
}

Subject: Redirect to IExternalPage link?
What is the most direct method of generating an IExternalPage url from
within a listener method in Tapestry 4?
I believe I want to throw a RedirectException to the page after a form
submission in order to prevent form resubmission and whatnot, but I am
having a hard time finding how to get the URL to an external page short
of
trying to guess it and construct it manually. It seems like there has to
be
a way to build the "official" link given the page name and the Object[]
of
parameters, but I haven't been able to find an example that works in
Tap4.
Thanks in advance,
Spencer
