NPE at user logout

Post by cristianpark »

Hi guys

I'm working on a simple chat (http://sourceforge.net/projects/chattered/) and I'm adding functionality (SQLLite user DB for remember logged user) and I want to make the logout process for the user (switch user) and when I fire the LogoutEvent I get a NPE. This is my output:

Code: Select all

You can go through my code on sourceforge, particulary this file [1] I launch the event on line 699 and receive the result on dispatch method (line 150), first thing I do is log the Event fired and I can't even get that when I launch LogoutEvent. Do you know how to solve this?

Thanks in advance

Will check it out - seems there is generally an error on logout/disconnect to be investigated and fixed.

Going to take at least 1+ week before it gets attention, as I'm hit by vacation and conference time

Hi, I am not able to reproduce the problem. Are you sure you are using the latest API available, version 1.0.1?
Thanks

Hi,

I'm getting a similar problem but at the Actionscript end. When the Logout Event is received I get the following output in Flash:
[SFS - INFO] Logout { Message id: 2 }
{ Dump: }

(utf_string) zn: GameZone

TypeError: Error #1009: Cannot access a property or method of a null object reference.

I've just patched, but the swc file doesn't seem to have updated. Any ideas?

Hi, please don't post Actionscript problems here, it's the Java forum.
Please start a new thread in the AS3 API forum
Thanks.

I see that the timestamp of that version is 03/05/2012 and I start working with SFS for Android about a couple of months so I think I have that version but I'm not sure, is there a way to check this?
Thanks

You can check the API version you're running by tracing the Version property from your SmartFox Instance

Terribly sorry, I just did a search for similar errors and hadn't realised which forum I was in. It seems these would have the same root cause. Any way, I have created a new thread in the Actionscript forum. http://forums.smartfoxserver.com/viewto ... 19&t=15188
