Simple case - I add a radio group to the form, attach it to local variable, set its visibility to "optional" and publish and it gives this error.
Component <radiobutton> has its default action behavior set to an invalid value, please set it to "optional", "required", "read only" or "hidden"
I have the value set to optional already !! It won't let me publish until i set the value to read only or hidden. What am i doing wrong, is this a bug?
