For Chrome, and I would assume any browser, you actually only need to delete the cookies that have "amazon" assuming you are running in the cloud. You don't need to restart anything, though logging out and back into Jasper is a very good idea.
Wondering how much work/re-work would be necessary with a change in primary/foreign keys. How well Jasper deals with composite keys, with already created views/reports/etc I realize a dropped/renamed table would cause too many implications, but curious as to ramifications of creating reports when schema changes will be likely. Thanks
