> According to Yahoo performance recommendations ([1], see "Post-load Compo=
nents"),
> visual components should be loaded on page load ({{onload}} event)
> to avoid heavy JavaScript processing before page is completely visually b=
uilt.
> In RichFaces, it is simple task using {{JavaScriptService}}, which enable=
s you to collect and inject JavaScript snippets which should be loaded usin=
g jQuery {{$(document).ready(...)}}.
> Thanks to CDK templates, it's also simple change in renderers, just move =
component contructor to newly created CDK tag {{<cdk:onloadScript>}}, which=
 would delegate to {{JavaScriptService}} (if {{JavaScriptService}} not foun=
d, processing may fall back to rendering {{<script>window.addEventHandler('=
load', ...)</script>}}, but this is optional part.
