Subject: [Mono-list] Strange Error When Populating A DataSet

When I populate a DataSet from a pretty simple SELECT statement, I=20
notice a strange error:

"Cannot set column Date to be null, please use dbnull instead"

This only happens when I include the Date column from the table (of type

DateTime, naturally), which is somewhat needed in the DataSet.  None of=20
the values in the column are null (the database won't allow it).  Also,=20
what makes it look even stranger is that, since this DataSet is the=20
return value of a web service, I can browse to the service directly and=20
see exactly what is being returned.  It looks like it works for a bit,=20
but then in the middle of some of the data it adds the error text and=20
throws the exception.

Any ideas what might be causing this?  For reference, I'm using Mono=20
1.0.6 (or, at least, I should be unless something went wrong when I=20
upgraded).
