[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-300) Propagate variable to parent conversation

Propagate variable to parent conversation ----------------------------------------- Key: JBSEAM-300 URL: http://jira.jboss.com/jira/browse/JBSEAM-300 Project: JBoss Seam Issue Type: Feature Request Components: Core Reporter: Raul Piaggio It is often desirable to output a value from a nested conversation to its parent. One possible way is to add a property to the @Out annotation (i.e.: @Out(scope=CONVERSATION, level=PARENT)). If there's no outer conversation it can propagate to SESSION. Alternatively, it can be explicited by the inner conversation via the @Begin or @End annotations. (i.e.: @Begin(nested=true, outputs="parameter1,parameter2"). The variables "parameter1" and "parameter2" would be promoted to the outer conversation when the inner one ends. I think @Begin is better since a conversation may end via a pageflow <end-conversation/>. Also, this is similar of how we usually declare methods in any language (output explicit in signature).
