If you are trying to stop your app from accidentally changing properties on WebPageType, I think it would be easier and safer to achieve this by marking WebPageType as ReadOnly in the mapping. Then you won't need to protect it via handling cascading in all its associations.
I think this is a misunderstanding of what cascading means.
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.
