Bob, I had similar trouble when I upgraded to MMNet 3.6. The cause turned out to be setting the NavControl to the grid. I didn't see that in your code but I thought I'd pass it along just in case.

>Hello. I have a business form with 1 grid, 2 textboxes, and 5 mm button controls. The grid and texboxes all have the same bindingsource. I have 1 BO which is set as the primary business object. When I click on my mmButtonNew I type in my data in my 2 texboxes. When I click on my mmButtonSave to save my new data I get an error that it cannot save. For some reason the framework wants me to data enter my new data in the grid and not in the textboxes. I'm using the grid for navigation only. Since the textboxes are bound to the same source and use the same binding source members as the grid why doesn't the BO pickup the data from my textboxes?
