As far as I understand you have a RulesAccepted field/property in your model definition. Based on the 1. issue the RulesAccepted property is not boolean, is this correct?
If yes - could you please clarify the following:
1. What is the type of the RulesAccepted and what is the purpose of the check box element? 2. How the validation should work in this case?
3. What should the state of the check box element indicate?
