Subject Re: Composite view from several "request" managed beans
Date Thu, 21 Aug 2008 08:02:02 GMT
Also can be possible to use for complex page compositor class as
managed bean - include in Compositor managed bean (Dashboard) others
managed beans.
Looks like I will prefere this, if anyone dont provide better idea
