I did, it's on my blog :) But I know what you mean! The bug is that 'variables' scope inside a component is supposed to be the private scope (and unnamed scopes default to 'variables' scope). > I thought the variable was automatically put into the this scope. I Nope. It's safer this way - you have to explicitly request a public variable. > have to agree with Hal on this one. That is a kludge. The scope should > have a name. A scope named private would have been a better option. And "this" would better be named "public" or something similar (however, since it compiles to Java, naming scopes as keywords is probably a bad idea). > Allow me to bang my head on the desk.

What exactly is overriding, then? Which book is that? Sounds like a bad one... Overriding is where you define a method in a base class and you 'override' that definition in a derived class. When you call the method on an instance of the derived type, you get the function from the derived class. If a function is only defined in the base class (and not overridden) then you can still call it on a derived instance (and get the base class version). Overloading is where you have more than one function - in the same scope - with the same name but different signatures (parameters). When you call the function, the compiler selects which signature to call based on the argument types. > You're right. When did this creep into the product?
