How long does ninja invisibility last?

[Doug McCrae]

The Ghost Step class feature allows a ninja to use a swift action to become invisible for 1 round. Does this invisibility last the whole round or does it stop once he attacks? If the latter, and the ninja has multiple attacks with one weapon, would his sudden strike damage only apply to the first attack made with that weapon?

He has the invisibility condition for one round. He does not have the limitations of the invisibility spell and can make multiple attacks.

Hmmm, I believe I read in the online eratta or somewhere that it actually works like greater invisibility.
