FacesContextHelperUtil

FacesContextHelperUtil is a convenience utility that reduces the boilerplate code required to add messages or scripts, find components, obtain request attributes, and more.

General Usage

A script can be added to the response via FacesContextHelperUtil.addScript(java.lang.String). The script will be written out at the bottom of the page (or in the <eval> section in a partial response) in the response of the current request.
