Subject Re: Get a list of pages in current application?
Date Sat, 03 Sep 2005 18:19:05 GMT
You can try an guess this way, but Tapestry is efficent and does not
keep (or need) such a list. It lazy loads pages on request so if a
request has not been made for a page, Tapestry knows nothing about it.
Plus pages can be built that have no .page file at all.
