Hello,
I have an entity "Payment Methods" that is N:1 to Accounts. So a customer may save various credit cards on their account for use. I have a two option set field on the Payment Methods entity for "default payment method." One of the records on the account needs to be the Default payment method. Only one of the Payment Methods on the account may be set to default.
What would be the best way to make sure only one record is set to default. I wish I could make a radio button that spanned records, but I know that is not possible.
I can do this in JavaScript - but am wondering if someone else has a different design.
Thanks for your help!
