Very nice - I'll do that. I still think it would be nice if Tapestry could check that required parameters have been set before the page is activated, and if I didn't have to write that activate() method myself. After all, nothing prevents callers from activating the page without setting its parameters first. And considering that the caller most likely will be some other page written by me, I am not entirely comfortable with that :-)
A nice solution, though - thanks.
