Subject Re: .NET cannot handle null date or decimal values sent by Axis 1.2.1
Date Tue, 19 Jul 2005 14:23:22 GMT
This is a known problem in .NET. It doesn't support nulls in a number
of different types. Rather than sending a null (nillable="true") you
have to simply not send the element (nillable="false" minOccurs="0").
