Hi,

I have following error here:

Following code:

CommonEntityBase entityBase = entityCore as CommonEntityBase;
CommonEntityBase cloneEntityBase = ( CommonEntityBase ) entityBase.GetEntityFactory( ).Create( );

string xmlData = string.Empty;
entityCore.WriteXml( out xmlData );
cloneEntityBase.ReadXml( xmlData );

During the WriteXml-Method some properties of type object are marked within the code as 'Type="Unknown"'. Due to this the ReadXml-Methods throws an NullReferenceException during read in method FieldUtilities.DetermineRealFullTypeName(...)

Any hints?

Using Version 2.6.9.903

Thanks

Christoph

entityCore.WriteXml( out xmlData );

What's the type of the entityCore object?

One of the generated entities which has CommonEntityBase as base class

I'm currently looking into it. One mistake was not to mark runtime properties as [NonSerialized]. But this did not solve the error with the object property.

Edit:

Ups, I've discovered that Properties can't be mark as 8NonSerialized]

So how can I exclude specific Properties from being serialized?

What's the .NET type of the property which has type generated as UnKnown? Could you please post the piece of XML holding the "unknown" value?

Ok I figured it out.

To prevent Properties from being serialized you have to mark them as [System.Xml.Serialization.XmlIgnore].

In this case I have following code:

        private object additionalInformation = null;
        public object AdditionalInformation
        {
            get { return this.additionalInformation; }
        }

Attributing the Property AdditionalInformation with the statement above solved my problem.

Thanks for your time walaa

Christoph
