Hi Terry,

Well, I spoke too soon. I've managed to get access to the real page
but it turns out that this fixes only about half of the problems
with the various page components (i.e., content coming from other
pages such as LeftMenu). This might be exposing a bug in page content
processing, dunno.

I now have the filter correctly passing the content through on
LeftMenu, LeftMenuFooter, CopyrightNotice (may be my own custom
page, can't remember), and TitleBlock (a custom page used inside
Header.jsp to provide header content).

It seems to matter *how* the page is accessed within the JSPs, but
I've not figured that part out yet. For example, LeftMenuFooter
is included in Favorites.jsp via:

      <wiki:InsertPage page="LeftMenuFooter" />

without any problem, but the content following "G'day," is getting
caught by the filter on

   <wiki:CheckRequestContext context='!login'>
   <wiki:UserCheck status="known">
   <wiki:Translate>[{TEST page='{$username}Favorites'

%%collapsebox-closed
! [My Favorites|{$username}Favorites]
[{InsertPage page='{$username}Favorites' }]
%% }]
   </wiki:Translate>
   </wiki:UserCheck>

In the above case I'm actually getting two copies of my error page,
with getRealPage() returning the name of the currently-requested
page which causes the filter to refuse and return the error message.
This means I end up with the error message intended for the content
area also showing up where that InsertPage plugin is instantiated.

If this is unclear I'll try to put up something on the wiki since
this all needs documentation anyway and it's mostly already written
in the javadocs.

... okay. I've just posted an initial (non-functioning) distribution,
a sample filters.xml and some docs at

    http://www.jspwiki.org/wiki/PermittedPageFilter

Any help appreciated...
