NPE at user logout

[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:

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

Thanks for your reply Thomas, I will be waiting for your revision.
Enjoy your vacation/conference time

Hi Thomas, did you check out this error? Do you need further information? Let me know if you need something or can guide me through fix the problem

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.

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

[rjgtav]

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

Thanks, I have 1.0.0, I tried 1.0.1 and it works great

Thanks for your help

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. viewtopic.php?f=19&t=15188
