title: XAML ItemsSource and SelectedItem binding declaration order does matter huh?
body: <p>I have observed a strange behavior, I have a XAML Combobox (SilverLight4) declaration with bound SelectedItem and ItemsSource and it appears that the order of SelectedItem and ItemsSource does matter... If SelectedItem is 2nd the control doesn't init properly (nothing is selected), if it was code I can understand why it matter because you can't select item which is not in combobox items collection, but this is XAML... </p>
  
  <p>Do I understand it right that XAML attributes order influences generated code line order? Or it's just something wrong with my code?</p>
