    beginning a conversation options

    System Administrator Expert

      In the Farley Practical Seam book, in the conversation chapter, there was a section that covers options when starting a conversation.


      Specifically, he stated that when using a page link request param (or perhaps s:link), you can begin a conversation by using propagation="begin" which begins the conversations prior to the start of the action method.


      When using @Begin, the conversation begins after the action method has finished executing.  He also mentioned that the method should return a non-null value IIRC.  What if the action method is public void?


      I have not read this info anywhere else, is it true?  If so, when would you need to use the s:link propagation="begin" instead of @Begin?  I've never found the @Begin to be an inappropriate option except when needing to restart a conversation when the user selects a new value in a drop-down, for example, and then I used the Conversation API for more fine-grained control of the conversation mgmt.
