I've not experienced that issue. Try to explicitly validate the property to
see if that's an issue with the DataForm or just with how you set up the
validation.
var ctx = new ValidationContext(this, null, null) { MemberName
= "NameOfYourPropertyGoesHere" };
var validationResults = new Collection<ValidationResult>();
if (Validator.TryValidateProperty("yourNewValueGoesHere", ctx,
validationResults))
// It was valid
else
// it wasn't valid, check the validationResults for details
Could you also try it with the example on the link I sent?
