Maybe the documentation is not clear ? What comes after 'AS' in an 
instanciation is the *event name* of the new object. You should use a string, 
but if you put a variable, then the contents of the variable will be used as 
event name. You were unlucky, as you used a object variable whose value is 
NULL, and so was translated into a void string.

Maybe I should force the use of a string constant after the AS...
