Dan Allen commented on JBSEAM-2153:
-----------------------------------

Actually, I had observed this issue as well and can explain the root cause:

The Seam redirect filter interferes with conversation switching because it allows page parameters to be added to the URL even though FacesManager works hard to keep them out of the redirect. The problem is not with ConversationEntry but rather the extra step added by <web:redirect-filter>.

What is interesting is that the redirect filter is not needed if you are using the Seam pages descriptor for navigation. It is only needed if you are still using faces-config.xml for navigation. The workaround is to disable the redirect filter when using Seam page navigation.

<web:redirect-filter url-pattern="NOPATTERN" />

A proper fix would be to pass along a token that tells the redirect filter not to apply page parameters in certain cases.

> ConversationEntry.redirect applies page parameters to the redirect.  Thus state in the redirected-to conversation is overwritten by state in the redirected-from conversation when:
> 1) The page parameter's value exists in the redirected-from conversation
> 2) The redirected-to conversation's view applies a page parameter with the same name
> If (2) doesn't happen it doesn't cause the state to be overwritten but we still end up with an incorrect url.
