Problems with properties

[shawn]

I was thinking that in Python2.4, all class definitions inherited from
new-style classes. There may be a bug here. I can make your code work
as expected by changing the class definition to:

class Task(object):


with that change, the assignment raises an attribute error. You could
also accomplish the same thing by eliminating the setNothing method and
defining your property as:

command=property(getCommand)

or for a really simple case like this, you could even leave off the
getCommand function and define the property as:

command=property(lambda self: self._command)

(although I am sure personal tastes vary as to style here).
