IIRC, .NET was mapping it to an enum data type, which is a value type and can't be null, but I could be remembering wrong.

It is strange that .NET would internally make a selection list an integer when it should be passed to Remedy in the XML as a string. Here is an example from a sample web service on a sample form here. This was pulled directly from the View WSDL tab in the Web Service definition window of the Admin tool (spacing added for readability). <xsd:complexType name="CreateInputMap"> <xsd:sequence> <xsd:element minOccurs="0" name="Character_Field" type="xsd:string" /> <xsd:element minOccurs="0" name="Date_Field" type="xsd:date" /> <xsd:element minOccurs="0" name="Date_Time_Field" type="xsd:dateTime" /> <xsd:element minOccurs="0" name="Real_Number_Field" type="xsd:double" /> <xsd:element name="Short_Description" type="xsd:string" /> <xsd:element minOccurs="0" name="Time_Field" type="xsd:time" /> <xsd:element name="Status" type="s0:StatusType" /> <xsd:element minOccurs="0" name="Integer_Field" type="xsd:int" /> <xsd:element minOccurs="0" name="Selection_List" type="s0:Selection_ListType" nillable="true" /> </xsd:sequence> </xsd:complexType> <xsd:simpleType name="StatusType"> <xsd:restriction base="xsd:string"> <xsd:enumeration value="Active" /> <xsd:enumeration value="Outdated" /> </xsd:restriction> </xsd:simpleType> <xsd:simpleType name="Selection_ListType"> <xsd:restriction base="xsd:string"> <xsd:enumeration value="Black" /> <xsd:enumeration value="Maroon" /> <xsd:enumeration value="Green" /> <xsd:enumeration value="Olive" /> <xsd:enumeration value="Blue" /> <xsd:enumeration value="Violet" /> <xsd:enumeration value="Teal" /> <xsd:enumeration value="Grey" /> <xsd:enumeration value="Silver" /> <xsd:enumeration value="Red" /> <xsd:enumeration value="Bright Green" /> <xsd:enumeration value="Yellow" /> <xsd:enumeration value="Light Blue" /> <xsd:enumeration value="Fushia" /> <xsd:enumeration value="Aqua" /> <xsd:enumeration value="White" /> </xsd:restriction> </xsd:simpleType> As you can see the Status field and Selection_List fields are a restriction base of string. In the above example the Status field can't be Null of course while Selection_List can be.

Lyle, did you have the same problem as I described? For integer field, datetime field, it is ok as long as you set nillable=true, minOccurs=0 on the output mapping. But for drop-down list field (which is enumeration type in WSDL), the value cannot be empty. I found out that the workaround is to add an empty enumeration value. This way even customer select "(clear)" for that drop-down list field, serialization will be ok on my .Net client. The .NET framework for working with web services creates a class that represents the web service for use in your application. Selection fields (or dates or other numerical fields) get represented by numbers, DateTimes, or enums which can't be null in .NET, because they are value types and not reference types. As a result, any time you try to retrieve a record that has NULL in one of those fields, you will get an error. The work around we found was to manually edit the WSDL after you create the web service and change the type of all of those fields to a string. String is a reference type and can be null, so you will no longer get the error. If you need to work with the values in the correct data type in your .NET code, you can convert the string to the desired data type after retrieving it from the web service and then work with it that way.
