I have a many to many relationship between 2 entities, incident *-* category In the incident object we have a boolean and we would like the radio button widget to only show when certain categories are selected using input reference set selector to specify the categories. Regards,
On you incident entity you can set another boolean variable (showCheckBox)
When adding or removing a categegory, you can check if the incident is still associated with a category that requires showing the checkbox. If so, set it to true else set it to false. Now refresh you incident and you should only see the checkbox when necessary.
