Unless you cast on the defensive, casting a spell in a threatened square provokes an AoO. But what if you start casting a spell with a casting time of 1 round (or more) and then someone move next to you? Does he get an AoO since you are still casting a spell? Can you provoke an AoO only when you start casting a spell, or anytime during your spellcasting?
No, he shouldn't get an AoO per the Core Rulebook page 187 under the Cast a Spell Entry fourth paragraph: "You only provoke an attack of opportunity when you begin casting a spell, even though you might continue casting for at least 1 full round."
Now that doesn't stop the attacker from using a standard action to cause damage and disrupt your spell, but that someone isn't getting a freebie either.

Ok that's what I thought, but I just wanted to be sure, thank you!
