[Mono-dev] Bug with XML Serialization

[knocte]

Hello,

With VS.NET2003 I am able to serialize a class without errors, but with 
Mono I obtain the following exception:

System.InvalidOperationException: System.Collections.IList cannot be serialized because it is an interface
in <0x00142> System.Xml.Serialization.ReflectionHelper:CheckSerializableType (System.Type type, Boolean allowPrivateConstructors)
in <0x000cd> System.Xml.Serialization.XmlReflectionImporter:ImportListMapping (System.Type type, System.Xml.Serialization.XmlRootAttribute root, System.String defaultNamespace, System.Xml.Serialization.XmlAttributes atts, Int32 nestingLevel)

in <0x00233> System.Web.HttpApplication+ExecuteHandlerState:Execute ()
in <0x0007c> System.Web.HttpApplication+StateMachine:ExecuteState (IStateHandler state, System.Boolean readysync)

I am trying to deploy a website using Maverick.NET+Apache+mod_mono.

The portion of code that may conflict with this is:

  [XmlInclude(typeof(CAccion3A))]
  public class Query : ControllerProtected {
 
    protected string cuenta;
    protected string nombreEmpresa;
    protected string operacion;
 
    protected CAccion3A[] actions3A;
 
    public IList Actions3A 
    {
      get {
        if (this.actions3A == null)
              return new ArrayList();
        return new ArrayList(this.actions3A);
      }
    }

[...]

The result of the serialization using Microsoft runtime is:

<?xml version="1.0"?>
<Query xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

    <anyType xsi:type="CAccion3A">

    </anyType>
    <anyType xsi:type="CAccion3A">

      <Nombre />
      <Apellido1 />
      <Apellido2 />
      <Email />

      <Direccion>0</Direccion>
      <Numero />
      <Piso />
      <Puerta />
      <CodigoPostal />
      <Poblacion />
      <Pais>ES</Pais>

      <Telefono />

      <Objetivos />
    </anyType>
  </Actions3A>
  <Cuenta />
  <NombreEmpresa>enterprise</NombreEmpresa>
  <Operacion>busquedaPorEmpresa</Operacion>
</Query>

If the IList doesn't contain any members, serialization should fallback 
to "<Actions3A />".

Should I file a bug report? (I am using Mono 1.1.8.2.)

Regards,

    Andrew
