Polymorphic Form

Polymorhpic Form is a SOLoist sample application that demonstrates how a form can change depending on the type of the selected object that is provided on the form's input pin.

Selecting a Bank Adviser object (as a subkind of Person) from the combo box on the left will display a details form with an additional field Bank Name.

The implementation uses a GUIConformsToFilter component that selects one of the panels in a deck to show, according to the type of the object provided on its input pin.
