If forms are used polymorphically—not only for the type for which they are defined, but also for subtypes of that type that do not have their own form definitions—it should be possible to include a special group in the form that displays the attributes of these subtypes in a generic manner.
Test
- Create Type A with subtype B; define a form for Type A with the group “Additional Attributes.” Generate a table containing As and Bs and display the selection in a form. When an A is selected from the table, the attributes described in the form definition should be displayed. When a B is selected, the “Additional Attributes” group should appear.
