OK the underlying problem here is that the Binding does not have a Path specified, therefore, the binding framework does not know which property name to look out for when handling PropertyChanged events. So I have fabricated a Path for the binding in order for change notification to work.
I don't necessarily like answering my own questions but I have found a solution to my problem. I've been able to keep my original flow and address the idiosyncrocies of SL4 data-binding. And the code seems a bit cleaner, too.
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.
