It’s not entirely clear to me what you’re asking.
`getItemList` will return whatever it returns—if the logic for what should
return lies in the view layer then it’s an architectural problem.
If you need to return two lists then you should have two list getters. If
the view layer *presentation* of the list varies by list content then the
list should be presented in a structure that represents that, e.g.,
Class ViewList {
String representation; // e.g., “radio”, “dropdown”, etc.
List items; // The things to show
}
If it depends on actions *taken* in the view layer, e.g., something
JavaScript-y, then all this is out the window and we’d need more
information.
