I have an external table called Students and an external table called Languages. Each student can have multiple languages.
In AIM, I'm trying to create a Student form containing a Languages widget that would allow the user to select multiple languages. The Students table contains a reference attribute to the Languages table called Languages. However, in the Configurator, the "Multiple Allowed" checkbox is greyed out, I guess because I'm working with external tables. It seems like this should be a simple thing and a common use case, so I must be missing something obvious. How can I get this to work?
