With @PerNestedConversation the component instance that exists in the parent conversation is invisible to its child conversations.

Why are u using @PerNestedConversation if you want to acces the parent conversation?

I think you should be using

@Begin(nested=true)

Here the nested conversation uses the same instance as that of parent

In that case. try this

import org.jboss.seam.core.Conversation;

String parentId = Conversation.instance().get.getParentId();
ConversationEntry parentConversationEntry = ConversationEntries.getInstance().getConversationEntry(parentId);

// play with ur parentConversationEntry here
// parentConversationEntry.
