NPE when lag monitor not enabled

I'm seeing a NullPointer exception in the Java client during logout when the lag monitor is not enabled:

Code: Select all

java.lang.NullPointerException

Does the Java client support running without the lag monitor?

Great, thanks for the quick fix.

Any idea when the new client API will be available?

This seems to be happening again with client API of the new version. I go back to release 3 and it works again.

With "new version" are you referring to the SmartFoxServer 2.1.0 patch? Because it doesn't contain the API. All API updates are available here: http://www.smartfoxserver.com/download/sfs2x#p=updates

Ok. I meant the libraries on the final release. I will download the updates then.
Thanks.

I'm facing this too with the newest version available on download links. All I do is

Code: Select all

sfsClient.send(new LogoutRequest());
as you can see on my code here [1], the event is launched when the user is loged and joined into a room (in a simple chat) and he/she press the back button (back to login screen), I register the listener but I can't get to the log on the dispatch method since I'm having the null pointer error

Thanks in advance
