我正在将我的应用程序从RichFaces 3.3.3迁移到Richfaces 4.0.0。我在Richfaces 4.0.0中解决了与删除标记相关的几个错误。
现在我在加载主页时遇到以下异常。

我还观察到org.richfaces.component.Positioning.bl的值为.bl的枚举值不可用。
我在其他罐子里也经过验证，但是bl没有Enum vulue。
我无法理解，为什么我会得到这个例外。
答案 0 :(得分：2)
你的一段代码试图将“bl”传递给处理枚举的方法。它正在通过EL解析器，因此它可能位于XHMTL页面上。
rich:dropDownMenu用于定位弹出元素，我的猜测是问题在{{1}}和@jointPoint，因为那是唯一一个在文档中提到“bl”的人。在RichFaces 4.X中，正确的值是“bottomLeft”。
