I don't see any problems with the code itself. The problem could be due
to another problem in the code elsewhere. Would you be able to send a
failing version of the code my way for me to test?
FYI: I recommend that you use the form of "array( &$this, 'function' )"
when passing an object's function. Passing $this by reference allows
PHP4 to play nicely. Otherwise, you'll run into really odd issues on PHP4.
