Problem serializing primitive data using WCF

Scenario: WCF client app, calling a web-service (JAVA) operation, wich requires a complex object as parameter. Already got the metadata.

Problem: The operation has some required fields. One of them is a enum. In the SOAP sent, isnt the field above (generated metadata) - Im using WCF diagnostics and Windows Service Trace Viewer:

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "2.0.50727.3082")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(TypeName="Consult-Filter", Namespace="http://webserviceX.org/")]
public partial class ConsFilter : object, System.ComponentModel.INotifyPropertyChanged {

    private PersonType customerTypeField;

Property:

[System.Xml.Serialization.XmlElementAttribute("customer-type", Form=System.Xml.Schema.XmlSchemaForm.Unqualified, Order=1)]
    public PersonType customerType {
        get {
            return this.customerTypeField;
        }
        set {
            this.customerTypeField = value;
            this.RaisePropertyChanged("customerType");
        }
    }

The enum:

[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "2.0.50727.3082")]
    [System.SerializableAttribute()]
    [System.Xml.Serialization.XmlTypeAttribute(TypeName="Person-Type", Namespace="http://webserviceX.or开发者_运维知识库g/")]
    public enum PersonType {

        /// <remarks/>
        F,

        /// <remarks/>
        J,
    }

Operation metadata:

[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
[System.ServiceModel.MessageContractAttribute(IsWrapped=false)]
public partial class consultRequest {

    [System.ServiceModel.MessageBodyMemberAttribute(Namespace="http://webserviceX.org/", Order=0)]
    [System.Xml.Serialization.XmlElementAttribute(IsNullable=true)]
    public ServiceClient.ConsultServiceReference.ConsFilter filter;

    public consultRequest() {
    }

    public consultRequest(ServiceClient.ConsultServiceReference.ConsFilter filter) {
        this.filter = filter;
    }
}

The trace log:

    <MessageLogTraceRecord>

When using the XML Serializer to serialize primitive types which have minOccurs="0" in the XML Schema, there is an additional property added. It is named *Specified. In your case, I expect you have a boolean property named customerTypeSpecified. You will need to set it to true whenever you need the customerType to be sent.

Simple question: if you instantiate the object normally and write it out to the console or System.Diagnostics.WriteLine explicitly using XmlSerializer, do you see the same behavior?
