Price field results in NaN with one product attribute

If a product attribute is given only one choice with a dropdown list and it is set as required then the price shows as NaN. I realize that a one option dropdown is not a choice but it will show the attribute on the receipt/invoice for the customer.

Thanks for info. This issue is already fixed and a fix will be available in the next release.

Thanks for the fast response. The radio option works with only one option and we can change back to dropdown in the next release....jeff
