When I rerender a component with "defaultChecked" or "defaultValue" react fails to update the "value" and "checked" attribute accordingly.

Before you say "use a controlled input" I would argue that this is a bug as it basically disallows uncontrolled forms with "reset" buttons. (It will always reset to whatever the initial default value was).

name="fruit"
                defaultChecked={true}
                onChange={emptyFunction}
              />
            </form>
          </div>
        );
      },
    });
    var stub = ReactTestUtils.renderIntoDocument(<RadioGroup />);
    var aNode = ReactDOM.findDOMNode(stub.refs.a);
    var bNode = ReactDOM.findDOMNode(stub.refs.b);
    var cNode = ReactDOM.findDOMNode(stub.refs.c);
    expect(aNode.checked).toBe(true);
    expect(bNode.checked).toBe(false);
    
    expect(cNode.checked).toBe(true);
    bNode.checked = true;
    
    
    
    aNode.checked = false;
    expect(cNode.checked).toBe(true);
    
    ReactTestUtils.Simulate.change(bNode);
    
    expect(aNode.checked).toBe(true);
    expect(cNode.checked).toBe(true);
  });
  it('should support ReactLink', function() {
