Slide And Get Up

[BillyMac]

In a scrimmage yesterday, a player, in my partner's primary coverage area, slid on the floor several feet to get a loose ball, obtained possession on the floor, left the ball on the floor, got up, and picked up the ball. My partner called a travel violation. At first I mentally questioned my partner, but then I went back to what I've been taught about sliding on the floor, and what you can legally do once you stop sliding: sit up if you're on your back, pass, shoot, start a dribble, or call time out. Since this act wasn't on my legal list, I decided that my partner had made a good call. Is my legal list complete? Are both of us correct? Citations please, both for and against.
