Description
If a TextField inside a RadioGroup has a ValidationError, processing of AjaxFormChoiceComponentUpdatingBehavior will erroneously update the group's model:
- RadioGroup#validate() does not convert the input, because #isValid() returns false (since the nested textfield has an error message)
- the behavior tests #hasErrorMessage() on the group, which returns false (since the group itself doesn't have an error message)
- the behavior continues processing with a null value
