Flex won't display a child of a container movie clip

[royalrapier]

I have a Container Movie clip called frameContainer in wich I load new Frames( a symbol from flash), with this function:



var i:Number=0;
frameContainer.x=48;
xPos=0;
do
{
frames.push(new Frame());
frameContainer.addChild(frames[i]);
slideshow.push(false);
frames[i].index=i;
frames[i].f.width=frameWidth;
frames[i].f.height=frameHeight;
frames[i].x=xPos;
frames[i].y=0;
xPos+=frames[i].f.width+10;
frames[i].f.addEventListener(MouseEvent.MOUSE_UP,fMouseClic kOnFrame,false,0,tru e);
i++;
}while(xPos<200)



frameNumber=i;
this.addChild(frameContainer);





The previous function works great.And I have a function called addNewFrame() which adds a new Frame at the end:



private function addNewFrame():void
{
frames.push(new Frame());
frameContainer.addChild(frames[frameNumber]);
frames[frameNumber].f.width=frameWidth;
frames[frameNumber].f.height=frameHeight;
frames[frameNumber].x=xPos;
frames[frameNumber].index=frameNumber;
xPos+=frames[frameNumber].width+10;
frameNumber++;
frames[frameNumber-1].f.addEventListener(MouseEvent.CLICK,fMouseClickOn Frame,fa lse,0,true);
}



But, for some reason, the new frame can't be seen. When I type just

addChild(frames[frameNumber]);

(instead of frameContainer.addChild(frames[frameNumber]) )



it works great. Also I can access the new frame with the getChildAt method, the only, and biggest problem is that I can't see that new frame when I add it as a child of the frameContainer movie clip.



Can someone please help
