>             Project: JBoss Seam
>          Issue Type: Feature Request
>          Components: Core
>            Reporter: Christian Bauer
>         Assigned To: Gavin King
>            Priority: Minor
>             Fix For: 1.2.1.GA
>         Attachments: navigation-patch.diff, ReturnToCapturedViewNavigationHandler.java, ReturnToParentViewNavigationHandler.java
> It's about my favorite subject, the "history" or "cancel" button.
> Assume the following (RC == Root Conversation, NC == Nested Conversation):
> RC(1) -> NC(2) -> NC(3)
> I can render a Cancel button on each page in NC 2 and 3 with the action=#{conversation.endAndRedirect()} to get back to any parent NC or RC.
> I can not render a Cancel button on each page in RC, because there is no "parent view-id" we could redirect to. So my Cancel button on these pages has to call some logic I've written on my RC backing component.
> I propose to extend the Conversation.endAndRedirect() method with the following logic:
> - If called in a NC, do what it currently does.
> - If called in a RC, check if the 'redirect' component is present in RC, if yes, call 'redirect.execute()'
> If this would be available, I could completely control conversation navigation and the navigation history through nesting conversations (with s:link or pages.xml) and by ensuring that a RC has a prepared 'redirect' component when it is started. All Cancel buttons would be able to use action="#{conversation.endAndRedirect()}" and would either get the user "one up" in the conversation stack or "out" of conversational scope.
