我正在使用带有Tomcat 7.0的JSF实现Mojarra 2.0.3-FCS，当我尝试使用任何类型的JSF验证器和复合组件时发生错误。 在这个例子中，我在inputText上使用了f：validateLength，一旦我得到一个小于最小值的值，就会发生异常，而不是显示vlidation错误消息，请你帮我理解一下这个错误的来源：

注意：相同的代码正在使用GlassFish 3.1.2
答案 0 :(得分：2)
看起来只是使用JSF实现中的一个错误。
我正在使用JSF实现Mojarra 2.0.3-FCS
这已经快5岁了（2010年7月）。 currently已经在2。29。29（2014年7月）。或者，当您使用Servlet 3.0兼容容器时（Tomcat 7），请使用最新的2.2.x，目前是2。2。9（2014年12月）。
注意：相同的代码正在使用GlassFish 3.1.2
这只能证实这是Mojarra的一个错误。使用Mojarra 2.1.6进行封底。
作为初学者，当您看到来自API / impl本身而不是来自您的代码的异常时，请始终查看您是否正在使用最新版本的API / impl并进行升级。如果仍然无法解决问题，请在issue tracker中查看，或在此处提问：）
