First of all, thank you for this excellent framework, I have personally learned a lot from it..
To the point now .I downloaded 2.1.4 and in the file CCDirector.cpp at line 586, the NULL assertion of the pScene should be == instead of !(=.
I hope I make sense and my observation is correct.
If not, I would appreciate it if you could explain why it isn't.
Thanks in advance,
Keep up the good work)!
