Connect vs Disconnect with UserEvent.SYNCHRONIZATION_CHANGE

Question

I'm using the UserEvent.SYNCHRONIZATION_CHANGE event to determine when the current user connects or disconnects from a room. Since SYNCHRONIZATION_CHANGE fires for both loging in and logging out, what is the best way to distinguish between the connecting and disconnecting?http://livedocs.adobe.com/labs/acrobatcom/com/adobe/rtc/events/UserEvent.html#SYNCHRONIZAT ION_CHANGE

Answer 1

Thanks for your response. I have two quesitons.
1) I wasn't able to find the example you mentioned (sharedModel/SharedManager). I found sampleApps/SharedModel/*, but didn't see SharedManager classes in there. Where can I find these classes?
2) I misunderstood you when you said "You can look for isSynchronized property in your  ConnectSession/CollectionNode". I started watching cSession.isSynchronized, which works for the first time you enter a room, but if you leave a room and enter another, cSession.isSynchronized does not do what I'm expecting (true = logging in, false = logging out). Which isSynchronized should I be monitoring? Here's an example of what I'm currently doing and some associated output that is not doing what I expect. I know that looking at cSession.isSynchronized, but could you show me how to modify my example to work correctly?

Output:
