Cannot restore Object from Instance state: parsing error
===

I am trying to restore an array of Objects from a `savedInstanceState`. I added each one to the `Bundle` individually here: (rhythm is the array of Objects)

    @Override
	public void onSaveInstanceState(Bundle outState){
		outState.putInt("numParts",rhythm.length);
		for(int index = 0;index<rhythm.length;++index){
			outState.putSerializable(""+index,rhythm[index].beat);
		}
		super.onSaveInstanceState(outState);
	}
When the `onRestoreInstanceState()` method is called, I try to assign my `rhythm` array with the Objects from the Instance State here: (it isn't null)

    @Override 
    public void onRestoreInstanceState(Bundle savedInstanceState){
        rhythm = new Part[savedInstanceState.getInt("numParts")];
        for(int index = 0; index<rhythm.length;++index){
        	 Object middleMan =savedInstanceState.getSerializable(""+index);
        	 if(middleMan==null){
        		 System.out.println("It's null...");
        	 }
       	rhythm[index]=(Part) middleMan;
        }
    }
It throws a `ClassCastException` when I parse to a `Part` every time. Part implements `Serializable`. Why is it not allowing me to parse? Will I need to do custom serialization? 
Please help!
