//register in the namespace
AmpUI.Form.FBuilder.registerClass("AmpUI.Form.FBuilder", Sys.UI.Control);
if (typeof (Sys) !== "undefined") Sys.Application.notifyScriptLoaded();
Is it special? for example, i never understand the addHandlder and removeHandler in the Javascript function and also WHAT IS registerNamespace AND WHAT IS Sys.Application.notifyScriptLoaded();?
