This could be, I am trying to compare against one of my working versions to see what is different. I do not have any strange or special code.

Can you paste more of your code that registers and calls the business objects?
Also, paste what you have in Xaml to set the binding context and where it is set.

Check you have a primary key set on the action table in SQL
Check what the PrimaryKey property is set to in the action biz obj.
