Drag & Drop

[Pierre Goupil]

Hello,

I'm currently playing with AJAX in Wicket using WicketStuff YUI integration.

Is there any way to refuse a drop ? There's a behavior called Droppable
which includes an accept() method but I can't figure out how to add it to my
component tree / call it.

Here's a working code snippet :

-----
final WebMarkupContainer list1;

        final List<String> list1items = new ArrayList<String>();
        list1items.add("1.1");
        list1items.add("1.2");

        add(list1 = new WebMarkupContainer("list1"));
        list1.setOutputMarkupId(true);

list1.add(new YuiDDTarget("LIST") {
            private static final long serialVersionUID =
-62687283825213344L;

            @Override
            public void onDrop(AjaxRequestTarget target, Component
component) {
                String newItem = ((ListItem<String>)
component).getModelObject();
                list1items.add(newItem);
                target.addComponent(list1);
            }

        });

-----

But then, I'm trying to add a new Droppable() to my list1 component but
neither onDrop() nor accept() are called :

-----
Droppable d = new Droppable() {

       private static final long serialVersionUID = -3647700662771836452L;
            @Override
            protected boolean accept(Draggable draggable) {
                return super.accept(draggable);
            }

            @Override
            public void onDrop(AjaxRequestTarget target, Component
component, int index) {
            }

        };
list1.add(d);
-----


A clue, anyone ?

Regards,

Pierre
