add array to a NSMutableArray ?

[syndrome]

I have this method:

		
for(CCSprite *sprite in mySprites){
		 
		CGPoint posizioneActual = sprite.position;
		NSInteger posizioneInt = 0;

		if (i determine the position of the sprite) posizioneInt = ..;
		else if..
		else if..

NSInteger spriteRotation = 0;
		
		if(sprite.rotation == -90) spriteRotation = 1;
		else if(sprite.rotation == 0) spriteRotation = 2;
		else if(sprite.rotation == 90) spriteRotation = 3;
		else if(sprite.rotation == 180) spriteRotation = 4;

NSArray *lastPosition = [NSArray arrayWithObjects:[NSNumber numberWithInt:posizioneInt], [NSNumber numberWithInt:spriteRotation], nil];

		[actualState addObject:lastPosition];

actualState is a NSMutableArray, and I want to add all the position of the sprite (now contained in lastPosition) in actualState, so I have an array that contains other arrays.

But [actualState addObject:lastPosition]; doesn't work, the console sais:

2011-02-18 10:19:12.664 game[28165:207] actualState count = 0

Maybe I have to transform my array to add it as an object... but how?

Where do you create actualState?
