popTo() has not been attached yet

[luziqi123]

在使用最新版的时候调用popTo()方法报出了 has not been attached yet 错误。
一点一点debug发现在onHiddenChanged的时候调用了一个 onFragmentShownWhenNotResumed() 方法。在这个方法调用了mFragment.getChildFragmentManager(); 然而在之前的一大堆方法调用中已经触发Fragment的mHose = null的操作了，所以就报错了。。
�我目前的解决办法是在前面做一个判断，现在我的VisibleDelegate.java下dispatchChildOnFragmentShownWhenNotResumed方法长这样儿：

    private void dispatchChildOnFragmentShownWhenNotResumed() {
        if (!mFragment.isAdded()) {
            return;
        }
        FragmentManager fragmentManager = mFragment.getChildFragmentManager();
        List<Fragment> childFragments = fragmentManager.getFragments();
        if (childFragments != null) {
            for (Fragment child : childFragments) {
                if (child instanceof ISupportFragment && !child.isHidden() && child.getUserVisibleHint()) {
                    ((ISupportFragment) child).getSupportDelegate().getVisibleDelegate().onFragmentShownWhenNotResumed();
                }
            }
        }
    }

请问大佬上述代码要加在哪个地方，我全局搜索没有找到VisibleDelegate相关的类啊，望指点
