Question

So here’s what I mean.
Let’s say I have a class ErrorMessages which holds all my error messages as static constants. So I could access them like ErrorMessages.PASSWORD_INVALID or ErrorMessage.PASSWORD_TOO_SHORT. I want to know if it is possible to have separate classes that hold subset of these constants and access them like ErrorMessages.PASSWORD.INVALID or ErrorMessages.PASSWORD.TOO_SHORT, etc.
This way I can more structured static structure and makes it much easier to use autocomplete.
I tried few different ways and couldn’t figure out if this was possible..

Declare them as const Objects in the static class – you won’t get them in auto complete though.

public class ErrorMessages
{
  public static const PASSWORD:Object = {
     INVALID:"invalid password",
     TOO_SHORT:"minimum 6 chars required",
     TOO_LONG:"100 chars: r u sure?"
  };
  public static const FILE:Object = {
     NOT_FOUND:"No such file",
     READ_ONLY:"it is readonly",
     SOMETHING_ELSE:"something else"
  };
}

trace(ErrorMessages.PASSWORD.INVALID);

If auto complete is important, create a dedicated com.domain.errors package and declare different classes for different categories of errors (like PASSWORD, FILE etc) within that package. Now declare public static constants inside those classes as appropriate.
