I have a BO which I would like to have access to 2 more related BOs.  The idea is to have a property in the Parent BO to the ChildBO and in this ChildBO to another Child like this:

CustomersBO.OrdersBO.OrderItemsBO.ItemPrice

How can I do that for SF Business Object?

Humm,

This is getting better when changing the code as follow:

I now get an error when trying to use this property in a code like this:

Look at the attached image for the error: NullReferenceException was unhandled by user code.  Object reference not set to an instance of an object.

What I understand about this error is that I would need to create an instance of this object in order to use this property, while when using the original method there was not need to do that, guess because previous method was always creating an instance of the class with this code:

Dim loLookupBO As New InsuranceCompanyBO

When you call new row, I think is just adds a new row to the data table, with the values being set to whatever is the default for their type. For strings, that is Nothing (null), hence the error.



Don't forget the other part of the code, which is to set values of that new row:





Do this right after you call NewRow()

Greg,

So far, the error has nothing to do with setting values to the created new row.  When using BO.NewRow() SF will populate it with the default values which are good enough in my case.

In order to make it work I added a "New" command to initialize the Private BO variable like this:

Then I made some changes to the property code to make sure the BO is filled all the time, like this:

So far the code above is working fine.
