> Key: RF-11822
> URL: https://issues.jboss.org/browse/RF-11822
> Project: RichFaces
> Issue Type: Feature Request
> Security Level: Public(Everyone can see)
> Components: cdk, resource handling
> Affects Versions: 4.1.0.Final
> Reporter: Lukáš Fryč
> Labels: yahoo_performance_recommendations
> Fix For: 4.3-Tracking
>
>
> According to Yahoo performance recommendations ([1], see "Post-load
> Components"),
> visual components should be loaded on page load ({{onload}} event)
> to avoid heavy JavaScript processing before page is completely visually built.
> In RichFaces, it is simple task using {{JavaScriptService}}, which enables
> you to collect and inject JavaScript snippets which should be loaded using
> 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 found,
> processing may fall back to rendering
> {{<script>window.addEventHandler('load', ...)</script>}}, but this is
> optional part.
