Hi All

It's been a while since I read the book and i'm perhaps being a bit lazy here posting my question before I research the answer. A also have to admit I haven't kept upto date since the version 2.0 book was released.

But, I am receiving the following error whilst trying to convert a ReadOnlyListBase to a DataSet:

My Class is declared as follows:

[Serializable]

public class EnquiryList : ReadOnlyListBase<EnquiryList, EnquiryItem>

{

..Code omoitted...

}

I have call my factory method to populate my list:

public static EnquiryList GetEnquiryList(int LocationID, int ExecutiveID, int CommunicationTypeID, int EnquirySourcID,

and have validated the list is populated.

My error occurs when I call the following method from my UI:

DataSet Ds = new DataSet();

Csla.Data.DataMapper.Map(list, Ds, supress);

The error I get (at runtime) is:

System.ArgumentException was unhandled by user code
Message="Property copy failed (RaiseListChangedEvents)"

I am using version 2.1 of the framework.

Any ideas please?
