It seems to work for me, could you please tell more about your
environment:
* Which version of OSX?
* Are you using /usr/bin/python or a custom install?
* Which version of PyObjC are you using (python -c 'import objc; print
objc.__version__')
BTW. The script I tested with is:
# begin of file
from Cocoa import *
import datetime
a = NSMutableArray.array()
c = NSArrayController.alloc().initWithContent_(a)
a.addObject_(datetime.datetime.now())
print a
c.rearrangeObjects()
# end of file
Could you create a small standalone program what demonstrates the
problem? A GUI tool would be fine.
