How to change all component values of parent panel on change of child panel in wicket

Question

In wicket I have created dynamic panels (parent panel) using list view in which I have to display the slider for that I have created another panel(child panel) to display the slider. Now the slider is created for each panel. On change of the slider in child panel I should do some calculation and change the values in parent panel where i moved the slider without refresh the page. is there any way to achieve this in wicket without using javascript

Answer 1

The "Wicket way" would be to use Wicket Events with Broadcast.BUBBLE. See example of Wicket events at http://www.wicket-library.com/wicket-examples-6.0.x/events/ and some documentation at http://ci.apache.org/projects/wicket/guide/6.x/guide/advanced.html#advanced_2.

Send an event up to the parent. The event payload may bring the AjaxRequestTarget so that the parent can repaint itself if needed.
