In other words, when there is a validation error, etc, Component#error (or #info, #warn, etc.) are called. Typically, you add a FeedbackPanel to the page and this displays the messages as <ul><li>message 1</li><li>message 2</li></ul> Instead of using the built in FeedbackPanel, just write your own (look at FeedbackPanel for help on how to get / clear the messages, etc). It can render them into a dialog, toaster, etc. -- Jeremy Thomerson http://www.wickettraining.com
