Add properties to BusinessList?

Hello,

is it okay to add standard CSLA properties to a BusinessList object?
I have defined the following classes:

ContactEdit : BusinessBase<ContactEdit> (Root Editable Object)
ConnectionList : BusinessListBase<ConnectionList, ConnectionEdit> (Editable Child List)
ConnectionEdit : BusinessBase<ConnectionEdit> (Editable Child)

Basically, the contact contains a collection of connections.
Now I want to declare one of these connections as primary connection.
My intension is to add a property to the ConnectionList as following:
public PropertyInfo<ConnectionEdit> PrimaryConnectionProperty;

Is this a valid approach? Is there a better approach to archieve this goal?

Thanks, alex.

Okay, found it for myself within the Csla books.

For everyone reading this, you have to add an intermediate class containing both the List and the default item like this:

ContactEdit : BusinessBase<ContactEdit> (Root Editable Object)
ContactConnectionsEdit : BusinessBase<ContactConnectionsEdit> (Editable Child, containing the default property and the List property.)
ConnectionList : BusinessListBase<ConnectionList, ConnectionEdit> (Editable Child List)
ConnectionEdit : BusinessBase<ConnectionEdit> (Editable Child)
