[Springframework-developer] Should DataBinder be an interface?

Hi,

In writing unit tests for my Controllers, I find I need to test the
initBinder method and test what I place inside the binder (via
registerCustomEditor).

I tried mocking the DataBinder class w/ easymock + cglib extension, but
it would generate an NPE.  The easymock list thinks this is a bug in
their code, though haven't heard from them since.

Is there a reason not to move (at some point) DataBinder to an
interface?  This would help with testing and mocks.  Another option
would be to create a MockDataBinder and add it to the spring-mocks.

Any thoughts?

Thanks!
Seth
