onRestoreInstanceState error

[RoelRoel]

  /**
   * Called when Android restores the activity.
   */
  @Override
  protected void onRestoreInstanceState(Parcelable state) {
    if (state == null || !state.getClass().equals(SavedState.class)) {
      super.onRestoreInstanceState(state);
      setTheDate(((SavedState) state).dateValue);
    } else {
      SavedState s = (SavedState) state;
      super.onRestoreInstanceState(s.getSuperState());
      setTheDate(s.dateValue);
    }
  }

This gives java.lang.ClassCastException: android.view.AbsSavedState$1 cannot be cast to org.bostonandroid.datepreference.DatePreference$SavedState
at line 3 of the funciton (setTheDate(((SavedState) state).dateValue);)

I get the same error when rotating Activity with Fragment containing DatePreference.

I'm trying to run with following code (unfortunately I don't fully understand the reason for creating the class SavedState when there is only one attribute and why there is different handling when isPersistent() is true). This is only a blind try...

  protected void onRestoreInstanceState(Parcelable state) {
    if (state instanceof SavedState) {
      SavedState s = (SavedState) state;
      super.onRestoreInstanceState(s.getSuperState());
      setTheDate(s.dateValue);
    } else {
      super.onRestoreInstanceState(state);
    }
  }
