> Based on the work done, it is more clear about what we need. When a tabPanel, contains dynamic tabs handle by the same backing-bean (because of the same include xhtml), we need a way, a reliable manner to initialize the backing bean when the user switch from a tab to another tab. It might be a specific tag, as  rich:bean init="#{.....initialize(params)}". This tab should be executed first, before any other calls of the backing bean whatever its place inside the xhtml page. If several such tags exist wherever (template, include), they must be executed in their natural order, from the deeper to the top of the page hierarchy.
> So, what we need is a contextual initialization, because the @PostContruct is not well suitable for that situation and also a more simple solution rather trying to do it by the PhaseListener (and what about the context???).
