I can't reproduce this in CVS: Using the ui example I am able to select a title, exit the conversation, go back to the page, select please select, and see that selected on the refreshed page and subsequent visits.
The difference between your example and mine is that I am not exiting the conversation.
When I load my start page, the conversation begins. I click on a link in my search results and that record is loaded in a 'view' screen. When I go back to the search screen, I'm still in my conversation and my search results are present.
This is possibly an incorrect use of a conversation. It works well for what I desire to show on the screen and limit my hits to the database, but I'm also in a state where the conversation never really ends.
I still can't reproduce, whether or not I end the conversation. Can you either provide steps to reproduce on one of the examples or submit a simple testcase with instructions on how to reproduce?
