There is not really enough code in your post to figure out what is going on. What you have posted will not effect the delegate call back functionality, other than the line where you set the actual delegate. Since you are setting the delegate correctly, you should be getting the callback.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
