Hi Sven, thanks.
The onRemove method is from the class
com.googlecode.wicket.jquery.ui.interaction.sortable.Sortable:
@Override
public void onRemove(AjaxRequestTarget target, String item) {
super.onRemove(target, item);
}
Why is the payload processed in this method, as it takes the target as
parameter? Is there another way to render the other panel or rewrite the
payload?
br, Chris
