nineoldandroids exception util

Question

I am having an issue using nineoldandroids. My Logcat is:

06-17 18:46:59.810: E/AndroidRuntime(1576): FATAL EXCEPTION: main
06-17 18:46:59.810: E/AndroidRuntime(1576): java.lang.StackOverflowError

06-17 18:46:59.810: E/AndroidRuntime(1576):     at com.nineoldandroids.util.IntProperty.set(IntProperty.java:43)

and my code is:

button.setOnClickListener(new View.OnClickListener() {

                public void onClick(View v) {

                    ObjectAnimator objectAnimator= ObjectAnimator.ofInt(miscrol, "scrollY", 0, 480).setDuration(duration);
                    objectAnimator.start();

                }
            });

What I am doing wrong? thank you.
