SOAP - problem with deserialization of array of custom objects

Hi.

I`ve got some problems when deserilizing array of objects in one of the web services. The following class was generated by the dotnet-svcutil and during deserialization countField is deserilized properly while the clientsField which is of type clientDetails[] is always null.

/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("dotnet-svcutil", "0.5.0.0")]
//[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.Xml.Serialization.SoapTypeAttribute(Namespace="http://www.example.org/ResellerAPI/")]
public partial class clientDetailsArray
{
    private int countField;
    private clientDetails[] clientsField;
    /// <remarks/>
    public int count
    {
        get
        {
            return this.countField;
        }
        set
        {
            this.countField = value;
        }
    }
    /// <remarks/>
    public clientDetails[] clients
    {
        get
        {
            return this.clientsField;
        }
        set
        {
            this.clientsField = value;
        }
    }
}

As far as I debugged it the source XML structure received from web service is correct and the problem must be with the code responsible for deserilization. When I enable XML debugging and step into the whole process I can find the following piece of code that is theoretically responsible for deserilization of the clientsField and it returns null no matther what:

        object Read610_Array() {
            // dummy array method
            UnknownNode(null);
            return null;
        }

Why is this method generated in such way and how to fix it?
