I have a task like this:

@task
def test():
    time.sleep(10)
    test.update_state(state="PROGRESS")
    time.sleep(10)
    return "done"

I then run this:

>>> from celery.execute import send_task
>>> t = send_task("testcelery.test")
>>> t.state
'PENDING'
>>> t.state
'PROGRESS'

I can see in the worker that the task has completed:

[2011-02-19 20:18:43,851: INFO/MainProcess] Task testcelery.test[7598b170-2877-4d76-89a0-9bcc4c9f877e] succeeded in 20.0225799084s: ‘done’

But t.state never changes from PROGRESS to SUCCESS. What am I doing wrong?

You should upgrade to Celery 2.2.4 (released yesterday) as it fixes the bug that causes this.
