First-chance exception when trying to init CCDirector* pDirector in onEnter

cocos2d-x C++
#1

Hey , im porting cocos2d game to be cocos2d-x version i have this simple code that gives me this exception :
First-chance exception at 0x00B6A6C3 in mygame_port.win32.exe: 0xC0000005: Access violation reading location 0xFEEEFEEE.
note that i checked all exceptions types under Debug ~~> Exceptions window .
the problem that i dont understand is if i remove the content of onEnter function every thing is working fine
but when i keep the onEnter content that is what you see here : im getting the exception
this is the code i have :

<pre>
class MAPlayfieldLayer : public CCLayer
{
public :
MAPlayfieldLayer;
virtual void onEnter;
virtual bool init ;
CREATE_FUNC ;
}

@bool MAPlayfieldLayer::init {
if ) return false;
this~~>setTouchEnabled(true);
//Add the score display to the screen
generateScoreDisplay();
//Add the timer display to the screen

this~~>scheduleUpdate;
return true;
}

void MAPlayfieldLayer::onEnter
{
CCLayer::onEnter;
CCDirector* pDirector = CCDirector::sharedDirector;
pDirector~~>getTouchDispatcher()->addTargetedDelegate(this, 0, true);

}

void MAPlayfieldLayer::update(float dt)
{
gemsMoving = false;

if(gemsInPlay->data!=NULL)
{
//See if we have any gems currently moving
CCObject aGemIt = NULL;
CCARRAY_FOREACH
{
MAGemaGem = static_cast<MAGem*>(aGemIt);
if (aGem->getGemState() == kGemMoving) {
gemsMoving = true;
break;
}
}

}
}

here is also my stack print :
