Hi,
Tiles use its own RequestProcessor extending the Struts one. You
don't have to declare it, but the Tiles plugin install it for you. As
you also use your own processor, your application fail. The solution is
to let your RequestProcessor extends the Tiles one, and install your
processor as before.
Tiles plugin checks if your RequestProcessor is compatible. Normally
an error message should have been provided somewhere ...
