gus888 - I don't completely understand what you are after, but if you are in an long running conversation, then if you try to begin another you will get an exception unless you use join=true. If you always want to rejoin an existing conversation when you hit @Begin, then just add join=true. Or design your application so that a user can never hit a @Begin from inside a conversation (certainly possible to do).
