The problem is that something is causing the dropdown to try to set its
KeyValue to the empty string. According to the traceback:

...since _setValue() is being called, it got a value of "" from the
call to the bizobj's getFieldVal() call. That would mean that you have a blank
record in your dataset (or at least one with a blank ProvinceState value). Are
you by chance automatically calling new() at some point in this process?

There seems to be an event that is causing the form to want to update
itself, which is the source of the second error:

It's the same error, because the underlying condition (blank value
returned from getFieldVal()) hasn't changed.
