Nicklas Karlsson commented on JBSEAM-1383:
------------------------------------------

One possible usecase could be some sort of "application transaction" where you fork the conversation and "rollback" just means to discard the fork and resume where you split off...

> I think the ability to clone a conversation would be useful.
> Currently if I have an s:link and I do an  "open in new window" on that link I now have 2 windows linked to the same conversation which may produce undesirable side effects to the user.
> So the idea is with s:link or other "GET" types of requests where the user might be inclined to do an "Open in new Window" type of operation we add the ability to clone the conversation when executed.  If applied to an s:link the conversation would always be cloned when that link is executed.  That way if the user did do an "Open in new window" each window would have 2 independent conversations.
> This would obviously have the side effect of an orphaned conversation if the user didn't do an "open in new window or tab" so the user would have to weigh the cost of creating orphaned conversations against maintaining the Conversation per window type of semantics this feature would provide.
