[Wicket-user] Is there a shuttle(?) component?

[Bruno Borges]

I don't know how to name it, but "Shuttle" was the name I've seen people using to specify this kind of component:

 ________        ________
| Item 1 |  >>  | Item 3 |
| Item 2 |  >   | Item 4 |
|        |      |        |
|        |  <   |        |
|________|  <<  |________|

Where:

>> : move all right
>   : move all selected right
... same, but to left side

If there's nothing like this ready-to-use, can somebody shot an idea on how to implement? Some first steps would be nice... :)

In the model, would be something like:

- In the left <select>, a list of "available" categories
- In the right <select>, a list of "associated" categories

I think on something like this:

ShuttleList s = new ShuttleList("shuttle", new ShuttleModel(availableItems, selectedItems) {
    public void populateItem(Item i) {
        ...
    }
}));

And then:

List newSelectedItems ((ShuttleModel) s.getModel()).getSelectedItems();

Now, 'newSelectedItems' should have objects that came from 'availableItems' and shouldn't have objects removed from 'selectedItems'.
