我对OmniFaces 1.11有一个类级别的问题（）

基本上，我尝试根据我单击的按钮，使用两个验证组验证同一个bean：

            <h:commandButton value="Mandatory">
                <o:validateBean value="#{testBean.pojo}" validationGroups="bo.ihm.beans.Mandatory" />
            </h:commandButton>

            <h:commandButton value="Optional">
                <o:validateBean value="#{testBean.pojo}" validationGroups="javax.validation.groups.Default" />
            </h:commandButton>

        builder.append("Pojo [forain=");
        builder.append(forain);
        builder.append(", cleSecuriteSociale=");

完整的代码可以在just run clean jetty:run war et go to上找到

第二页是演示类级约束不起作用的页面，当我单击Anywhere按钮时，我会得到如下验证错误消息：“Pojo[forain=false，cleSecuriteSociale=22，numeroSecuriteSociale=2531257351038，mandatory=null]无效“

结果是隐式EL强制导致了这一切。我们传递了内部值，如

ValueExpressionType.PROPERTY

和

ValueExpressionType.METHOD

，以指示EL表达式是表示属性（getter/setter）调用还是表示方法（action）调用。但是，如果该值具有隐式EL强制支持（如

java.lang.Boolean

），则该方法失败，在该值上，EL将隐式地将字符串

“true”

转换为布尔值

true

这种传递内部值以指示EL表达式类型的方法是因为OmniFaces 2.0用于在中分解EL表达式并提取任何EL方法参数，以便将它们转换并作为HTTP查询字符串参数传递。这就解释了为什么它在OmniFaces1.x中仍然运行良好

根据，OmniFaces 2.2已修复此问题。

复制后，错误由h:selectBooleanCheckbox触发（删除它，问题消失）。我们将对此进行调查并修复2.2。谢谢。我已降级到1.10版，无法重现此问题。我会问一个新问题，因为它在课堂上的表现与我认为的不一样。
