[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)

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?
