can't find Zone.getRoom method

[endquote]

I'm occasionally getting the following stack trace from Smartfox 1.5.5:

Code: Select all

The only place in my code where Zone.getRoom() is called within handleInternalEvent when handling the userLost event, which seems to agree with the stack trace (SmartFoxServer.lostConnection).

Code: Select all

var room = _server.getCurrentZone().getRoom(event.roomIds[0]);

These seems to happen randomly. Is there any explanation?

[Lapo]

the explanation is that you're passing an undefined as the argument to the method, and the java runtime complains about the fact that it doesn't exist a getRoom() method wich accepts an undefined value instead of an int
This is because getRoom is a Java method.
You should make sure that the passed value is != undefined
