Hi Maxim, Seems its a common question in the jquery-ui world... The best I can propose you for now is something like the following code. It does *not* use revert, but use a clone helper. This example is also using a browser-native "confirm" dialog...
Inspired from http://jsfiddle.net/WbHAr/1/ Draggable: Draggable<Book> draggable = new Draggable<Book>("draggable", model) { @Override public void onConfigure(JQueryBehavior behavior) { super.onConfigure(behavior); behavior.setOption("helper", "'clone'"); } }; Droppable: final Droppable<Void> droppable = new Droppable<Void>("card") { @Override public JQueryBehavior newWidgetBehavior(String selector) { return new DroppableBehavior(selector, this) { @Override protected JQueryAjaxBehavior newOnDropAjaxBehavior(IJQueryAjaxAware source) { return new OnDropAjaxBehavior(source) { @Override public CharSequence getCallbackFunctionBody(CallbackParameter... parameters) { return String.format("if (confirm('Drop here?')) { $(this).append(ui.draggable); %s}", super.getCallbackFunctionBody(parameters)); } }; } }; } Hope this helps :) Sebastien On Fri, Aug 5, 2016 at 2:16 PM, Maxim Solodovnik <solomax...@gmail.com> wrote: > Hello Sebastian, > > Is it possible to show confirmation dialog on drop (even pure JS or Wicket) > and "revert" file if user choose cancel? > > -- > WBR > Maxim aka solomax >
