Is there something wrong with Swing's MVC implementation for JList?

Question

Some time ago I asked this question. All solutions are workarounds.

Now this can\'t be. I feel that something is wrong here, but I can\'t tell if it is Swing\'s MVC

Answer 1

This is expected behaviour.

From Model-View-Controller [Wikipedia]:

In event-driven systems, the model notifies observers (usually views) when the information changes so that they can react.

So, when you call setSelectedIndex on the JList, you are updating its model, which then notifies each ListSelectionListener. It wouldn't be MVC if you could "silently" update a model without letting anyone know.
