JSF 2.x Tip of the Day: jsf.js AJAX onEvent() and onError() Examples

I was looking for some information on what I could do with the jsf.js AJAX scripts in JSF. Specifically, I was wondering if I could do some event handling, and how it should be accomplished. I was surprised that there really was not a complete example that I could find. I did find some blog posts from Jim Driscoll and some comments on stackoverflow by +Bauke Scholtz which show a partial solution, but nothing complete.

I decided to combine the good parts of Jim's blog post with some of the goodies from +Bauke Scholtz to create a complete example. In this example, I use a solution from Jim to demonstrate the events that are returned from the onEvent() and onError() listeners.  Along with a common request... A spinner for AJAX requests.

Once you download, and run the code. You will see a spinner while the AJAX request is processing. In my case, I use a Thread.sleep(2000); to cause the spinner to display for a little while.

The code for project can be found here: jsf-ajax-demo




This is based on the primarily on the work published by Jim Driscoll and Bauke Scholz. This is just a more complete example  of what they mentioned in their articles.
