    Ravi -
    
    I think the idea here is that the consumer performs the search and displays
    an own portlet for each individual search result entry. So the decision on
    how to generate markup for the search result would be up to the producer.
    The scenario - at least from my understanding - should not describe one
    portlet displaying the results just as a special view state. Of course this
    would also be a valid option (maybe even a common one), but here the
    producer would perform the search, not the consumer.

    I don't understand why transient entities are created in this scenario. Why
    is the search results page creating the transient entities?
    I can think of a case where the search results page provides a set of
    clickable GIFs that correspond to the hotel services but NOT actually
    create transient entities at the Producer. If the user actually clicks on
    one of them, it is at that time the consumer requests the producer to
    create an entity (transient or persistent) and then embeds the output of
    the entity in its web page.
    
    Am I missing something?
    
    thanks,

    I think that this is a very good scenario where transient entities make
    sense.

    Alan,
    
    I think that one example scenario is a search results page, say for hotels,
    that dynamically displays multiple maps - a map for each hotel found.
    
    Assuming that maps are remote services, and assuming that the number of
    results is dynamic, the Consumer needs to create multiple copies of the map
    service. If we allow the Producer to determine the persistence state of
    those maps, that would mean that someone will have to take care of the
    lifetime of those maps. The Consumer can't, because the page may be gone
    without the Consumer never knowing about it (the user closes the browser
    window). The Producer can't, because it can't tell whether the Consumer has
    stored a reference to those maps as part of a design-time description of a
    user page.
    
    Is that along the lines of what you were looking for?
