JavaServer(tm) Faces components have a dynamic id. This can create problems when trying to access these components from JavaScript code on the client. I my case I wanted to do a very simple and common thing, set input focus on a specific field. One solution is to use a custom component called IDProxy (http://www.jsftutorials.net/proxyTag.html). This component makes it easy to obtain the dynamic
