I can't see a solution for what you are doing.
...
@Override
public void onClick(AjaxRequestTarget target) {
Panel panel = new MyPanel("panelId");
addOrReplace(panel);
target.addComponent(panel);
}
creates a NEW Panel and the NEW panel is a totally new object that does not
know anything about the ORIGINAL Panel. The AJAX response renders the NEW Panel
(with it's new class attribute but without the AJAX behaviors you've added to
the ORIGINAL Panel).
This also happens with Wickts builtin Behaviors. Try this
panel.add(new AjaxEventBehavior("onclick") {
@Override
protected void onEvent(AjaxRequestTarget target) {
System.out.println("clicked!");
}
});
This also disappears after you replace the panel within an AJAX call.
You can do two things:
1. ...
@Override
public void onClick(AjaxRequestTarget target) {
Panel panel = new MyPanel("panelId");
! panel.add(new DraggableBehavior());
addOrReplace(panel);
target.addComponent(panel);
}
! AND USE VERSION 0.3.5!
2. ...
@Override
public void onClick(AjaxRequestTarget target) {
! originalPanel.setDefaultModelObject(some new value);
! target.addComponent(originalPanel);
}
Good luck and let me know if it works for you!

Betreff: Re: WicketJQuery: Drag & drop behavior lost for components of AJAX
updated panels
Found that when panel is constructed like:
public MyPage() {
...
add(new MyPanel("panelId"));
...
}
markup of a draggable element is:
<span id="id123456" class="myClass ui-draggable" ... >[]</span>
However when:
...
@Override
public void onClick(AjaxRequestTarget target) {
Panel panel = new MyPanel("panelId");
addOrReplace(panel);
target.addComponent(panel);
}
markup of a draggable element is:
<span id="id123456" class="myClass" ... >[]</span>
that is 'ui-draggable' is not found (stripped ? not added?)
in 'class' attribute of draggable element.
Any help is welcommed,
Stefan
