That's correct behavior according to TAL specs. You can get silent error 
handling this way: <b tal:content="boldtext | nothing" />. It's the " | 
nothing" that tells TAL there's another option (though it's nothing) 
available for this value, so don't freak out if the first one's missing.

I have my own class that extends PHPTAL, and it automatically sets 
req/post, req/get, req/cookie and a few others.
