As readers here may know I'm working on an app that records class, student and other details for a certain type of school.
I created a class called "ClassRegister" but when I fired up OA I couldn't get it to do anything with it. There's nothing special in the class itself, in fact I reduced the definition of the class to a single property and, for example, it won't let me select an ID field. When I select a property of the class in the treeview all of the input controls after "Transient" checkbox on the right hand side of the form are missing; not just disabled but not visible.
Just changing the name of the class, or event just changing the capitalization of the name is sufficient to get OA back on track.
I couldn't find anything in the docs to suggest that "ClassRegister" was an excluded name and, to be honest, given that it is in a 'custom' namespace I'm surprised that it is, even if by default.
