That is funny, since I've started to work with Jasper that bug/feature was changing. In iReport it was on, I've became used to that. Then in Studio 6.3.0 it was off, then it became on in 6.4.0. And now off again in 6.5.0... Just to make it clear what I mean - I want values in Input parameters be kept after a run, even if I do modify something in report, so on next run I won't have to enter all values again.
