从今天早上开始的支持库的最后一个版本（Android Support Package v4 revision 11）应该支持嵌套片段。
在我的项目中，我有一个包含ViewPager的片段，而这个 ViewPager 包含几个片段。
我打电话getSupportFragmentManager()而不是getFragmentManager使用支持库的FragmentManager。
问题是我仍然遇到崩溃，例如：
java.lang.IllegalStateException: Recursive entry to executePendingTransactions

有什么我做错了吗？或者支持不支持真正的嵌套片段？
我的交易就这么简单：
getSupportFragmentManager().beginTransaction()
.replace(R.id.content, new MyFragment()).commit();
