The problem is that when you use the <begin-conversation> tag in pages.xml with a pageflow, any time the page is rendered Seam attemps to re-perform the conversation requirements. (starting, joining or creating a new nested one).

Note, this is ONLY a problem when using a pageflow, without a pageflow, everything runs fine. 
If you use @Begin annotations on a method with a pageflow, then everything is fine. 

It appears to only be when using begin-conversation in pages.xml with a pageflow.

For the difference options, here are the results : 

<begin-conversation> results in an error (beginning conversation from long running conversation)
<begin-conversation join="true"> works ok because it just joins the conversation it started first time it hit the page
<begin-conversation nested="true"> causes a new nested conversation to be created each time the page is rendered

Somewhat similar to issue http://jira.jboss.org/jira/browse/JBSEAM-608 which was related to the pageflow re-starting on each render, except now it is the conversation that is trying to re-start on each render.

At the end of my attached forum post, I describe why using just join=true is not a practical solution for more complex scenarios involving nested flows.
