我们正在从JSF 1.2升级到2.2，我们在升级特立尼达时遇到了障碍。
在 Trinidad 2.2.1 中，自定义提示分面时，数据表的详细信息戳将解析为 null。还有人知道为什么会这样吗？
这在Wildfly(10.1.0.Final(上用Mojarra 2.2.13.SP1，Java 8(1.8.0_131(，JSF 2.2和Trinidad 2.2.1进行了测试(问题也存在于2.2上(。

products.add(new Product(1, new ProductInfo("product 1", "1")));
products.add(new Product(2, new ProductInfo("product 2", "2")));
products.add(new Product(3, null));
seeded.set(true);
