Well… :> Quite most of us is using Composer right? In the code, to which you provided a link, there’s a message saying: “2.0.4 under development”. That means, that most of us are on 2.0.3 in which this bug isn’t fixed yet!
It is good to know, that this is a framework bug (at least for once it isn’t something, that I wasted! :>) and that it is fixed in 2.0.4. However, most of us must wait for the official release of 2.0.4 to get this fix, right?
