public class AjaxDisableComponentListener
extends AjaxCallListener

An AjaxCallListener to disable the associated component while the AJAX request is running. Please note that under the hood this class uses DOM attribute 'disabled' to disable a component, hence it can be used only with those HTML components that support this attribute. If you want to use it with other kinds of components you should override generateHandlerJavaScript(org.apache.wicket.Component, boolean) to generate the proper enable/disable JavaScript.
