Hello developers, I've just pushed a patch which renders the Event and IEventListener generic, parameterized by the type of event arguments they receive, reviews are welcome (note some preceding and succeeding patches): http://gerrit.ovirt.org/#/c/31194/ If merged, this should enable us to slowly remove unsafe casts, e.g. as is often done with PropertyChangedEventArgs. I have used this (in succeeding patches) to eliminate a couple of such coverity scan defects. It will also add a lot of IDE warnings until most events and listeners are properly parameterized, as was the case with the parameterization of EntityModel and ListModel... Yours, Lior.
