Hi Antonio,

I thought I had a handle on what you are saying below but I can't get it to work as I thought it would. Are you saying the code below should be in the business object, or the business entity object?

I put it in the Invoice entity object and it compiles OK. But when I want to reference the custName in a WPF business window (data binding set to the Invoice business object) I don't get the custName. No errors or anything; the custName just stays blank. I tried this both with and without the "public string custName" property being defined in the business object.

What am I missing to get this to work?

Guy

The entity has a GetBusinessObject() Method in order to get the Entity´s Business Object, and the Business Object has a ParentBizObj property, so you can define in your invoice Entity something like:

>        {
>            if (invObj.ParentBizObj != null)
>            {
>                CustomerObj custObj = invObj.ParentBizObj as CustomerObj;
>                if (custObj != null && custObj.Entity != null) custName = custObj.Entity.CustomerName;
>            }
>        }
>        return custName;
>    }
>}
