Invisibility, Haste & Sneak Attack

[melkoriii]

A rogue, with sneak attack and a ring of invisibility, uses the haste partial action to move and attack (while invisible) once to apply her sneak attack damage. Then for the Full-Attack action attacks the same person after the invisibility goes down... Does she apply sneak attack damage to those attacks as well?

IF this was an ambush attack then all attacks in the first round would be sneak attacks IF the Rogue has initiative. That is if the Rogue sneaks up and attacks he gets surprise (a partial action) then he gets another partial action from haste. Next round everyone rolls initiative. IF the Rogue goes first then all attacks are sneak attacks that round as everyone is flat-footed till they act.

For the Rogue I would do the two partial attacks then a full attack. Then use the partial haste action to activate the ring and go invisible again.
