related #512
If I open form and don't choose value in dropdown field, then it submits empty string as value. So the question is - what's the purpose of isValueRequired property. Shouldn't it also be detected as validation rule and give error that you can't submit empty value if field is required? Anyway I see some consistency problem here.
