Data Adapter Insert Failure -- dotnet distributed apps

Hello,

I have the strangest problem. I have a winforms
application that has a strongly typed dataset. There is
one main parent datatable "Customers" and a
child "Invoices". Inserting a new customer into the db
and then updating the dataset with the new row using the
adapter is no problem. But when I follow it with an
insert of a new invoice row(regardless of it being a new
customer row or an existing one), the insert into the db
works fine, but updating the dataset with the new row
throws a null object reference error somewhere in the
inner workings of .Net. I've tried manually updating the
row but I still get the same error.

Has anyone come across this before or is there any known

Hi,

Do you have a relation defined in dataset between customer and invoice?
(It isn't defined by default)
