It is not that the attribute data type has to match its
declared type, it is that the attribute type has to
match the data type of the variable it is being
associated with. So there is another layer of
obfuscation in there. And since this completely
undocumented error can occur in another part of the
code entirely from where the actual error shows up,
it is basically impossible to debug. How the solution
was discovered is beyond my understanding.

Cheers,

David
