Subject Re: validating existence of session attributes in all Actions

Unfortunately, the understanding I have is that Tiles is going to 
override the RequestProcessor when the plugin initializes itself.  Maybe 
that's a Cedric question.  Do you know what it does, Chuck?  I guess I 
could dig into the source for a definitive answer.  But it doesn't 
appear that RequestProcessors are additive at all, so if you subclass 
RequestProcessor and then use Tiles, the impression I have is that your 
RequestProcessor will not get used (since I am of the understanding that 
Tiles will use it's own RequestProcessor).  I suppose you could build 
your own RequestProcessor that extends the Tiles RequestProcessor - or 
maybe that contained a Tiles RequestProcessor (so you could delegate to 
it) ... but maybe I'm totally incorrect or missing something completely 

Please comment!  I'm confused now :-/
