... What's happening is that you're bitten by this problem. Basically, what happened is that you didn't register your controllers explicitly in your container. Unity tries to resolve unregistered concrete types for you, but because it can't resolve it (caused by an error in your configurat...

... There are numerous reasons why disabling the back button will not really work. Your best bet is to warn the user: window.onbeforeunload = function() { return "Your work will be lost."; }; This page does list a number of ways you could try to disable the back button, but none are guaranteed...

... if you know its name, but I don't know of any way to discover it automatically. Yet another snag in the quest for an elegant solution is the problem of setting up the prototype inheritance correctly. If your source object's prototype is Object, then simply creating a new general object with {} wil...

...les: on variables it doesn't instantiate the variable itself, i.e. doesn't allocate any memory. This needs to be done somewhere else. Thus it's important if you want to import the variable from somewhere else. For functions, this only tells the compiler that linkage is extern. As this is the default...

It appears that when you type in a number in Java, the compiler automatically reads it as an integer, which is why when you type in (long) 6000000000 (not in integer's range) it will complain that 6000000000 is not an integer. To correct this, I had to specify 6000000000L . I just learned abo...

...ependency of $http on the AuthService. I believe that what you did is actually the simplest way of doing it. You could also do this by: Registering the interceptor later (doing so in a run() block instead of a config() block might already do the trick). But can you guarantee that $http hasn't b...

I would like to load all objects that have a textual tag set to any of a small but arbitrary number of values from our database. The logical way to go about this in SQL would be to build an "IN" clause. JPQL allows for IN, but it seems to require me to specify every single parameter to IN directly (...
