Take a look at the RequestFactoryTest [LINK] in the GWT source code for examples. The testChangedEdit() [LINK] method is similar to what you're trying to write. It calls a find() method and then operates on the returned proxy in the onSuccess() method. A RequestContext isn't a long-lived object. It is only valid from the time that it is called to when you call fire() on it. It can be re-used only if the onFailure() or onViolation() method is called in your Receiver . An EntityProxy or ValueProxy returned via Receiver.onSuccess() represents a snapshot of server data. Thus, the proxy is immutable unless it is associated with a RequestContext by calling edit() . The proxies returned by RequestC

Based on your question and the follow-up comments, my understanding is that your repo's (recent) history looks as follows, * bb1d222 (HEAD, master) | * 832e8af (origin/master) |/ * 3293d35 where commit 832e8af corresponds to your failed attempt at refactoring the code. Under the assumption that you are the only contributor to the GitHub repository; nobody else has ever cloned or forked the GitHub repository (there is a way to find out [LINK] whether that's the case); and you would be happy to pretend that commit 832e8af never existed and you would like to land in the following situation * bb1d222 (HEAD, master, origin/master) | * 3293d35 Then (and only then), you can simply do a force push g

The IEEE 754 standard for floating-point numbers and their arithmetic defines "infinity" and "not a number" as valid values. They may not be "valid" in the sense of mathematically useful... but they're what the standard defines. Code that works with floating-point numbers expects those values from certain operations, and can check for / react to them if need be, so Swift respects the standard for FP math. There isn't a corresponding cross-language, CPU-independent standard for integer arithmetic. Outside of Swift, it's generally assumed that dividing integers by zero is a Bad Thing [this video] , because you don't necessarily know if it'll halt the program or produce an incorrect result. Swift's
