For some reason if I a add a field on the master page, when previewed it does not display the xml data assigned to the field.
I have a work around, but it looks messy and would prefer to resolve the problem correctly.
My work around is to create another field with the same name in the "Design view" layout, and change the presence to invisible. I don't even have to link it to the xml data, simply select Global as the default binding.
Any ideas what I have done wrong, I assume it's a simple setting somewhere but I have no idea what it is.
