I created a class for a saTextbox. It has several other classes it calls within the package.
var tb:saTextBox = new saTextBox();
addChild(tb);

When I try to removeChild(tb) it should set the var tb to null.
Well, it does not. It holds the Object saTextBox.
Any suggestions on why it doesn't set the variable to null?
Could there be variables within the saTextBox class that do not allow it null?
