All Implemented Interfaces:

public class LazyHttpConversationContextImpl extends HttpConversationContextImpl
An implementation of HttpConversationContext that is capable of lazy initialization. By default, the context is associated with a request and the active flag is set to true in the beginning of the request processing but the context is not initialized (cid not read and the state not restored) until the conversation context is first accessed. As a result, BusyConversationException or NonexistentConversationException may be thrown late in the request processing and any component invoking methods on ConversationScoped beans should be ready to catch these exceptions. Lazy initialization is mostly a workaround for https://issues.jboss.org/browse/CDI-411.
