> One caution though, about one specific item you mentioned several times: "... users entering a non-existing update site url ..."
I think entering an incorrect update site is a "normal" user action. The UI should give the user the information but this should not be logged as error. I suggest to open a bug report for p2 so that they do not report this error if the request is done via the user p2 installation dialog. 2014-10-09 20:23 GMT+02:00 David M Williams <david_willi...@us.ibm.com>: > Sound quite promising Marcel, not to mention cool! :) > > > > Don't be too quick to write all those off as "user error".
