[Twisted-Python] inlinecallbacks, unhandled error....where?

[steven meier]

hi,


ive got these two functions:
@inlineCallbacks
def getUserList():
reload_interval = yield getReloadInterval()
print "222", reload_interval

target_url = host + "/?ReloaderUserOnline"

body = urllib.urlencode({"reloadsequenz":reload_interval})
#body = '\r\n'
#headers = {'Content-Type': 'application/x-www-form-urlencoded'}

d = getPage(url = target_url, cookies=cookies, agent=useragent,
postdata=body,
method = 'POST',
headers=headers)

defer.returnValue(d)



i can see the output:
222 somenumber, so apparently getReloadInterval works. it returns some
magic number as expected



now i call getUserList from this function:
(response is 1, so d = getUserList gets evaluated)
but there i get:

222 5821
Unhandled error in Deferred (short version, complete error at the end)


Traceback (most recent call last):
File
"/home/julius/.local/lib/python2.7/site-packages/twisted/internet/defer.py", line 1184, in gotResult


def printLoginResult(response):
#we are in, login accepted
if response == ' 1':
print "we are in, get user list"
#printChat(response)

def printResult(result):
print repr(result)
d = getUserList()
d.addCallback(printResult)
d.addErrback(printResult)




why is printResult not run?
