[flexcoders] move effect Flex live doc example does not work

[hworke]

   Hello all,

   the example in this link does not work.
http://livedocs.adobe.com/flex/3/langref/mx/effects/Move.html

   The exact error message is:

Severity and Description        Path    Resource        Location        
Creation Time   Id

Type was not found or was not a compile-time constant: move.
[Generated code (use -keep to save): Path: move-generated.as, Line:
187, Column: 14]                move    Unknown 1101999455125   884


    Any idea why it is not working in my Flex builder?

    Regards...
