Bug report

RadioGroup Validation fails always when Component is bound to Model

Reproduction of the problem

1. Define a FormViewModel and set its data annotation to [Required]
2. Initialize a Form and pass it the FormViewModel
3. In the Form:

• set up Validation
• define an Item that uses the RadioGroup Editor

4. Run the application choose a RadioGroup option and submit the Form

Current behavior

All the inputs of the RadioGroup Component get the data-val-required property and validation always fails

Expected/desired behavior

The RadioGroup's Validation should succeed, if one of the options is selected

Environment
