Breaking News... JCP Works! - New JSF 1.2 Feature...
By pelegri on Feb 28, 2006
I could not resist the title... :-)
Jakob describes a late addition to the latest JSF 1.2 draft. The method invokeOnComponent() allows to pass a callback into a UI component tree to deal more easily with iterative Contexts. One of the motivators for this feature was AJAX, but it applies in general.
I'll ask Ed and Jacob for some code snippets and will post them later.
