I'm a newbie user and I've created a Maintenance Form with a Business Object and I put in 6 textbox fields the same way the demo shows. When the form appears, all of the buttons on the MaintenanceFormToolStrip are greyed out except I have an option to add 'New' items to the database. This is a populated MS Access DB with an autogenerated Primary Key. I'm using a ODBC connection.
If I choose to add New data just for the heck of it, I get the following exceptions.
MicroFour.StrataFrame.Business.BusinessLayerException was unhandled

I have a funny feeling this is going to be very obvious, but I think I need another pair of eyes!
