After some experiments I realized that:
1) If I start the Test page from the browser with
localhost:8080/application/Test.seam and I refresh the page a new conversation
is started. This is true if and only if I have a call to the TestBeam (ex
<h:outputText value="#{TestManager.property}"></h:outputText> or the dataTable)
If I have not a call to the TestBean the conversation is not even started.
Let me say that if I start the Test page directly from the browser the page
itself is 'detached' from the conversation, or in other words, the page can
starts a conversation but it is not able to be attached to it.
2) If I start the Test page from a different page (StartTest, which does not
start any conversation) and I start the TestPage calling the startPage method,
I am able to refresh the page as much I like without new conversation starts.
This is true even if I have <page view-id="/Test.jsp"
action="#{TestManager.onListLoad}" /> in the pages.xml. Obviously the table is
refreshed (it was my original problem !!).
Let me say that in this case the Test page is 'attached' to its conversation.
There is a clue of the 'attachement': the URL in the browser is:
localhost:8080/application/Test.seam?conversationId=number
3) Removing @Begin(join=true) from the findAll method no conversation at all is
started (!!! ???)
4) The behaviour is the same if I put the bean either into the SESSION or into
the CONVERSATION
Now, question is: How can I make the Test page knows that it is attached to a
conversation (or better that I will be attached to a conversation) when I start
it directly from the browser ?
Comments and help are welcome.
