Paladin Spells: Wisdom or Charisma

[David Holland 791]

A contradiction I noticed in the Pathfinder Beta: Under the Paladin section in the classes chapter, it claims that the number of spells you have is determined by your charisma score. You must have 10+spell level Charisma to cast a spell, the number of bonus scores is determined by your Cha modifier.

But in the chapter on attributes it lists Wisdom as the trait that determines what spells a Paladin can use, just like 3.x

So which is it, Wis or Cha? If it's Cha, then the Paladin no longer has any need for a decent Wis score.

This is a typo that has already been noticed here; Paladins use Charisma now to determine their spellcasting abilities.
However, a high Wisdom, although not mandatory, is still useful for a Paladin (for Sense Motive, Heal, and Will saves).
