-====== Polymorphic Sample ====== +====== Polymorphic Form ====== 
-This sample demonstrates how GUI can change depending on the class of selected object.+ 
 +**Polymorhpic Form** is a [[SOLoist Sample Applications|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.
