Hi Richard,

Can you post your custom expression code, so we can see where the 
problem comes from ?

The registry system is backward compatible you can still use simple 
functions.

Builtin function have moved to PHPTAL_TalesInternal.

To register a modifier using the the system you have to call :

PHPTAL_TalesRegistry::getInstance()->registerPrefix($prefix, $callback)

where $prefix is your tales expression modifier name
and $callback is a function name or an array(classname, methodname)

You can call builtin tales using :

PHPTAL_TalesInternal::* static methods

PHPTAL_TalesInternal::path($exp, $nothrow)
PHPTAL_TalesInternal::string($exp, $nothrow)
etc...

Best regards
Laurent
