Issue with the association control

Hello,

I have tried so many ways and compared this an existing implementation. Everything is setting right. But I get always this error.

Do you have an idea?

thank you

Hi, My users are seeing the same checkboxChanged error but our error message has far less detail. Any progress on resolving this issue?
