Ending all nested conversations of a parent conversation

[kipod]

I am using a breadcrumbs trail, as shown in Dan Allen's Seam in Action :

<h:form id="switcher">
   Workspace:
   <h:selectOneMenu value="#{switcher.conversationIdOrOutcome}">
      <f:selectItems value="#{switcher.selectItems}"/>
   </h:selectOneMenu>
   <h:commandButton action="#{switcher.select}" value="Switch"/>
</h:form>

When a trail exists, e.g. Shops - MyShop - EditShop, and the user clicks on
a node, e.g. MyShop, I would like (in addition to switching to the desired conversation) to destroy all its nested conversations (in my example: EditShop).

I've searched the APIs and can't seems to find ANY way to even list or access the current conversation's nested conversations.

Does anyone know how can this be done?
Thanks.

Oh, and by the way, does the removeAfterRedirect field the ConversationEntry class has, has anything to do with this?

I can't find any doc explaining this field...
What does it do? can it be set in pages.xml?

If you want Seam to have a nice declarative way of doing this, please vote for JBSEAM-3286
