Forcing a Form to have context

When students (and others) self-select a form in Sonia, they can choose the placement this form applies to.

Previously, the user could ignore this choice and, as a result, the form would not have the placement context that makes it work - for example Sonia wouldn't be able to determine the Supervisor or the name of the Site this form should reference.

Now, a form can have a setting that informs Sonia that the user MUST choose a placement context before the form can even be opened.  In addition, if the setting is there, Sonia will try to determine the context automatically - so if the student only has a single placement, it will be picked automatically without the student needing to specify the context.
