I'm afraid those values may be hard-coded into the list control. When I view the values available to me from the app, using the EAExample model, I see the following complexities available for a class: Easy, Medium, Complex
When I open the EAExample.eap, and view the values in table t_complexitytypes, I see these values: Extreme, High, Low, Medium, V.High, V.Low. I believe that either I'm mistaken in the assumption that the table t_complexitytypes is what's being queried for the class complexity types, or those values are provided by code.
