Alexandre,
I don't understand why your change would work. The login of 
aetools.unpackevent is as follows
def unpackevent():
	if there is a ---- direct object parameter:
		unpack it into parameters[----]
	while we've missed any other parameters:
		unpack these by name into parameters
	for all attributes we know about:
		if the attribute is present:
			unpack it into attributes

Your extra code (if there's no ---- direct object) handles a 
case that is already handled by the while loop just below....

Could you pack up a python script plus CodeWarrior 7.2 project 
that demonstrates your problem? Please state the problem exactly 
(i.e. Expected behaviour: xxxx Observed behaviour: xxxx).
