I attached a cdxml file for you to look at. In the file we have a
checkbox that has a DataSource set to "nonexistantObject". When I set the
dataSource in the file initially it does not throw an error. Good.
However, when I close the file and open it again I get this traceback:

AttributeError: 'controlMix' object has no attribute 'nonexistantObject'
Here is the trouble with the real world. I have a dialog that gets passed
bizobjs through it's __init__ method, which I have overrided in code. The
bizobj is stored as self.myBizobj. I set the DataSource property on
controls to self.Parent.myBizobj. When I run the form, everything is fine
and the DataSource is evaluated. However, if I open the form in the CD I
get this AttributeError. So, for the time being I am forced to manually
set DataSource and DataField values in the afterInitAll method.
When loading a CD file, objects declared in coded methods are not
recognized because we aren't creating the class. Therefore, any reference
should fail. The error should be thrown at Run Time, not in the CD...
