Your code seems correct, I think the problem could be somewhere else. To debug this issue do this.
Problem solved! I ran into someone who encountered the same problem. The cause is very strange: tinyurl.com/3fkg8bk (ZF Forums).
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.
