public class SimplePanel
extends Panel

A panel with fallback render functionality which allows the panel controls to be rendered if its template is not available.

By default Panel will render its template or throw exception if template is not found. Thus if you do not define a template for the Panel, an exception is raised.

SimplePanel on the other hand first checks if the template is available on the servlet context path or classpath and if template is not found, the panel controls are simply rendered in the order they were added.

In effect SimplePanel falls back to the default rendering of AbstractContainer if the Panel template is not found.
