logon.setCallback(new PageCallback(this));
Please check the JavaDoc (or code) for PageCallback; you'll see it is
roughly the equivalent of using the page service, not the external service.
Tapestry should include an ExternalCallback as well, but since it doesn't
you'll have to write your own (and, perhaps, add a suggestion to add it).
An ExternalCallback should store the name of the page, and the array of
parameters and can then get the page from the cycle, cast it to
IExternalPage, and invoke the callback method on it.
