Input parsing failure

Hello all.
I have a foot pedal hooked to an Arduino that sends a line formatted as such when the switches state changes:
"ButtonEvent":args[0]:args[1]:args[2]:args[3]
args[0] = 0 (down), or 1 (up)
args[1] = pin number
args[2] = default 0
args[3] = default 0
It gets received in one piece using serialEvent, and sent to the following function:
void parseInput(String input) {
println("Received: " + input);
String args[] = input.split(":");
println(args);
if (args[0] == "ButtonEvent") {
println("Button Event.");
if (args[2] == "2") {
println("Button 2. ");
if (args[1] == "0") {
myRobot.keyPress(KC);
println("KEY DOWN");
} else {
myRobot.keyRelease(KC);
println("KEY UP");
}
}
}
}
I get the following output every time I push the pedal down:
Received: ButtonEvent:0:2:0:0
[0] "ButtonEvent"
[1] "0"
[2] "2"
[3] "0"
[4] "0
"
And this when I let it back up:
Received: ButtonEvent:1:2:0:0
[0] "ButtonEvent"
[1] "1"
[2] "2"
[3] "0"
[4] "0
"
As you can tell, this is obviously not what the code is supposed to do, and It is not working. If I comment out the args[0] == "ButtonEvent" line, It still does not get the args[2] == "2".
The foot switch is connected to Pin 2, so that is normal. And argument 1 is fine. But the code seems to disagree. I have the multiple pin support so that I can expand it to 10 or so switches (Can, not will).
Any help would be greatly appreciated.
