Re: Something is missing in JSF?

[Mike Kienenberger <mk...@gmail.com>]

Yes, to summarize that thread:

Shale's ViewController wasn't intended to provide a generic managed
bean facility and is limited in what it provides.   It's probably not
what you want unless you have a single page-scoped bean you want to
manage.

If you're already using spring (or want to use Spring), the jsf-spring
integration library + Spring will provide this functionality.  
Implement InitializingBean and use afterPropertiesSet() instead of
init().

You can also create a "setInitialize()" setter as the last listed
managed bean property, and it's guaranteed to be called after all
previous properties are set.   This doesn't depend on any other
libraries, and can be used with any JSF implementation.   Thanks to
Simon for pointing this out.
