Even if it's not the default behaviour a @End(immediate = "true") feature seems like it would be useful. It would also help if sometime in the future the conversation lifecycle was documented in a bit more detail, although I realize it's a work in progress and that might take a while.

| Thanks for the tip. I hadn't noticed when that feature was added. Any idea how it works? Some type of unique token representing the current state that's placed in the component tree perhaps?

| My problem is that the next action after a list is displayed is often displaying a selection from the list. As I understand things, on a postback the DataTable component will reaccess the DataModel through EL variable resolution, then indicate the row selected. If the DataModel exists in a long running conversation, that will be returned and it'll work great. If the conversation wasn't started when the original DataModel was generated I'd imagine a new DataModel will be created on the postback (through the @Factory method) and it could be different from what was rendered to the user. Does that make sense?
