Receiving a nillable element from a .NET webservice using Blackberry

I have a .NET webservice sitting on my local IIS. I'm calling 1 method from it, ClientSearch, using a Blackberry. The method is:

[WebMethod]
public List<Client> ClientSearch(string Surname, string Forename, string DOB, string Postcode)
{
   List<Client> clients = new List<Client>();
   // Populate list
   return clients;
}

When I call this from my Blackberry simulator I get the error:

"not nillable element of array type in response is missed".

I'm accessing the webservice using stubs generated by the Sun Wireless Toolkit 2.5.2. The wsdl file for the client type contains:

<s:element minOccurs="0" maxO开发者_如何转开发ccurs="unbounded" name="Client" nillable="true" type="tns:Client" />

This is where the nillable comes from but the values are hardcoded in the web method so it should always have a value.

The code i'm using to call the webservice is the same as I use in every BB app to call them so I know that it works.

Service1Soap_Stub stub = new Service1Soap_Stub();
result = stub.clientSearch("", "", "", "");

I'm using Eclipse 3.4.0 (Ganymede) and the Blackberry JDE Plug-in 1.0.0.67 and component pack 4.5.0.

I've seen this on a few different forums but can't find how to solve this issue.

Solved the problem. The issue is that my Client object had some public properties that were never assigned a value too. I thought they would have the default values for their type but that wasn't the case.
