In visual studio 2010
If you set the text of the combo box, then try to either
a) set to it an empty string
b) right click and reset value
It will say property invalid (text can not be null)
And if you set the text, and then manually remove text from the xaml
It will also fail when it tries to build the page in the design window
(I suspect text is set to "string" instead of "string?" ??)
