I fixed it by implementing the supertabnavigator like this:
<------>
<?xml version="1.0" encoding="utf-8"?>
<SuperTabNavigator xmlns="flexlib.containers.*" 
    xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:Script>
        <![CDATA[
            public override function loadState(state:Object):void{
                if(state == null || this.numChildren == 1){
                    this.selectedIndex = 0;
                    return;
                }
                for(var i:int = 0; i < this.numChildren; i++){
                    if(this.getChildAt(i).name == state.selectedName){
                        this.selectedIndex = i;
                        return;
                    }
                }
            }
            public override function saveState():Object{
                var state:Object = {};
                state.selectedName = this.selectedChild.name;
                return state;
            }
        ]]>
    </mx:Script>

</SuperTabNavigator>
<------>
The tabs are just added like normal.

I think that this code should be included as the default in the 
supertabnavigator in
the next release.
