I have an editable form which includes radio buttons. Some use a text value for the 'hidden' value and a different text (spaces, brackets, etc) for the label - others use the same value for both value and label.
When the text value and label are the same, the field shows the existing field value by shoring the appropriate radio button as selected. But when the text values differ, no selected radio button is shown as if the field has no value.
Before I share the code (it is quite extensive and layered and I'd have to simplify), is this something you can replicate and thus a bug or something that doesn't occur for you? (I am using the latest update from a few days ago).
