The string '' is not a valid AllXsd value - meh?

Hello there - I'm quite new to WebServices and asp.net and I've exhausted my
troubleshooting capacity on this one.

I am running a lookup method against a remote webservice and am expecting
some data back. It would seem as if the response I am getting back is
actually missing a field and/or cannot be converted from '' (Blank?) to a
dataType.

On the face of it, it seems as if a dateTime conversion is failing - at
least from my limited view of things.

Is it possible to narrow down which property is being improperly formatted?

What other kinds of tests can I run?

Considering the WebService definition/proxy was built using the WSDL tool
from a schema file, how appropriate might it be to modify the resultant
service difinition in order to fix this (if I actually find what the problem
is!)?

Sincerely - n
