---------------------------------

Thank you very much.

I've updated the conversation: [Tab Panel backing bean isolation / attach data on tab / Bean initialization?|https://community.jboss.org/message/809305#809305]

We tried to migrate from 4.2.3 to 4.3.1 but we failed because of significant change into 4.3.1. This version is not back compatible and we need to adapt the code and figure out why some links does not perform anymore and so on... We are in production, not the right time to upgrade.

It will be nice for us having this bug solved or having some guide line or recommendations.
  - https://java.net/jira/browse/JAVASERVERFACES-2016
  - https://issues.jboss.org/browse/RF-12907

We have found clues about the problem, but not enough to understand the whole case. We do not have the time to debug third party stuff.

Is there a migration guide from 4.2.3 to 4.3.1 ? Until the version 4.2.3 we had success in following your continuous upgrade but not this time. Sorry.

> 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???).
