1045 Interface Questions AS3

Question

Hello,
I've recently decided to take a look at AS3, and I was in the
process of seeing what kind of changes I needed to do with my code
to make it AS3 compliant. I did the changes to import the
flash.display.MovieClip class. As I was going through this circular
pattern (compile, flash tells me what's wrong, I correct it...)
this one area has stumped me.
I get the following error: "1045: Interface newI was not
found."
What am I doing wrong? Are Interfaces allowed with AS3 code?
Thanks,
Kelly

While I do not know the problem, it appears AS 3.0 does still
have interface keyword:
"interface definition keyword
Usage
interface InterfaceName [extends InterfaceName ] {}
Language Version : ActionScript 3.0
Player Version : Flash Player 9
Defines an interface. Interfaces are data types that define a
set of methods; the methods must be defined by any class that
implements the interface.
An interface is similar to a class, with the following
important differences:
* Interfaces contain only declarations of methods, not their
implementation. That is, every class that implements an interface
must provide an implementation for each method declared in the
interface.
* Interface method definitions cannot have any attribute
such as public or private, but implemented methods must be marked
as public in the definition of the class that implements the
interface.
* Multiple interfaces can be inherited by an interface by
means of the extends statement, or by a class through the
implements statement.
Unlike ActionScript 2.0, ActionScript 3.0 allows the use of
getter and setter methods in interface definitions.
Note: To use this keyword, you must specify ActionScript 2.0
and Flash Player 6 or later in the Flash tab of your FLA file's
Publish Settings dialog box. This keyword is supported only when
used in external script files, not in scripts written in the
Actions panel.
