Hi there, In the "group" tutorial (http://mightyfingers.com/tutorials/display/group/) it seems super easy to acces group elements, but for me it doesn't work. I have a simple project here: http://mightyeditor.mightyfingers.com/#p266r If you look in the play.js you can see the code. It's basically like this: this.playScreen = mt.create("Game"); // create Game Group this.gPig = this.playScreen.Pig; // but cannot get the children console.log("pig:" + this.gPig); // undefined - But Why? Any advise what the problem might be?
