convertToWorldSpace not working as expected on rotated layer.

cocos2d-x C++
#1

I noticed this on Cocos2d-html5 and posted there but no one responded. So I decided to try it out on Cocos2d-x and there problem exists here too :P.

Basically if I rotate a layer that contains a sprite and then try to convert that sprite’s position to the world coordinates, I get values that are WAAAAY off.

    // This is a layer that has just been created, no other transformations have been done to it.

    CCSprite* sp = CCSprite::create();

    // Place sprite in middle of the screen.
    sp->setPosition(ccp(300, 400));
    addChild(sp);

    setRotation(-90);

    CCPoint p = convertToWorldSpace(sp->getPosition()); // I get (380, -1.3e-05)!!!

That is certainly not what I would expect, I would expect to remain at (300, 400). I’m not if I’m misunderstanding something here or it’s an issue in the framework.

Thoughts?
