This has given me a BIG pause while I'm working on a simpler example.
It may actually solve the problem.  


Are you saying that in order to create a Field that can be used as an
attribute of another class; I should define it in an interface and ONLY
in an interface?

Such like pseudo:

import Field
class IAbc(Interface)

myNewField = Field(
 ........

and then when I need to use it in a class, simply state that that class
implements(IAbc)?


If this is true I have a two month hard core re-factoring to do.

Cheers,
Tim

Thanks again.
