The first thing to make sure is to check of JGroups
message go from
one server to another both way, you can enable remote observation
module debug log for this (see
http://extensions.xwiki.org/xwiki/bin/view/Extension/Observation+Module+Rem…).
Done and checked: yes it works.
(all written down on http://jira.xwiki.org/browse/CURRIKI-5909)
There is several caches in XWiki and you maybe have
several of your
own so if jgroups properly send messages it mean some cache somewhere
corresponding to what you are viewing is not invalidated when
receiving an event.
Can it be it's invalidated too early?
This seems to be my best guess.
Then the older version is fetched from the DB.
When you can reproduce the issue the idea would be to
find what is the cache with the issue, it's not always easy to find out when you
don't know exactly all the caches but you can view all of
them using JMX (see
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Monitoring#HXWikiCaches…),
at least all the caches created through standard XWiki cache module.
Thus far, any such inconsistency, on production environments, is solved with a cache-clear
so this is likely.
I could find out by just emptying one or the other right?
