我在WildFly 8.1.0 final上访问XHTML页面时遇到以下异常。

我不在应用程序中使用任何CDI bean（它们都是JSF托管bean）。

以下是无关紧要的：

See the linked question instead.

编辑：

不幸的是，当OmniFaces（1.8.1）与PrimeFaces 5.1 final 一起添加到类路径时，会发生这种情况。

如果添加OminFaces（1.8.1）单独（没有PrimeFaces 5.1 final），则会导致抛出this异常（堆栈跟踪太长而无法容纳问题机构）。

在以下情况下，会发生上述异常（在代码段中，而不是在pastbin中）。

以下以JSF托管bean为例：

import java.io.Serializable;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;

@ManagedBean
@ViewScoped
public class TestManagedBean implements Serializable
{
    private String text;
    private static final long serialVersionUID=1L;
    public TestManagedBean() {}

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }
}

只需按照以下方式访问此bean（来自XHTML页面）。

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://xmlns.jcp.org/jsf/html">
    <h:head>
        <title>Facelet Title</title>
    </h:head>
    <h:body>
        <h:form>
            <h:inputText value="#{testManagedBean.text}"/>
            <h:commandButton value="Submit"/>
            <!--This button is not needed any more-->
        </h:form>
    </h:body>
</html>

这会抛出异常（如果您碰巧将OmniFaces（1.8.1）和PrimeFaces（5.1.0 final）添加到类路径中。）

当给定的JSF托管bean转换为CDI bean时，异常消失，如果它是CDI bean，则可以使用或不使用OmniFaces（1.8.1）。

import java.io.Serializable;
import javax.inject.Named;
import javax.faces.view.ViewScoped;

@Named
@ViewScoped
public class TestManagedBean implements Serializable
{
    private String text;
    private static final long serialVersionUID=1L;
    public TestManagedBean() {}

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }
}

最后，如果在XHTML页面上使用<o:viewParam>，如下所示，

<ui:define name="metaData">
    <f:metadata>
        <o:viewParam name="id" value="#{bean.property}"/>
    </f:metadata>
</ui:define>

然后在服务器终端上显示以下消息。名称metaData在主页面模板上定义，如下所示。

<ui:insert name="metaData"></ui:insert>

01:17:29,000 SEVERE [javax.enterprise.resource.webcontainer.jsf.application] (default task-30) JSF1068: Cannot instantiate component with component-type org.omnifaces.component.input.ViewParam

在空白项目（没有母版页模板）上，如果使用<o:viewParam>如下。

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:f="http://xmlns.jcp.org/jsf/core"
      xmlns:o="http://omnifaces.org/ui">
    <h:head>
        <title>Facelet Title</title>
    </h:head>
    <h:body>
        <f:metadata>
            <o:viewParam name="id" value="#{testManagedBean.id}" required="false"/>
        </f:metadata>

        <h:form>
            <h:inputText value="#{testManagedBean.text}"/>
            <h:commandButton value="Submit"/>
        </h:form>
    </h:body>
</html>

考虑上面提到的 CDI bean只有一个类型为String的额外属性id，它会抛出以下异常。

<o:viewParam>替换<f:viewParam>会抑制上述异常。

我不知道，如果这可能适用于更高版本的JSF，因为我仍然不知道如何在WildFly中更改JSF版本（8.1.0 final）（它使用JSF 2.2.6作为默认值）。与GlassFish不同，我可以在服务器目录中的某处找到javax.faces.jar文件，可以用更新的JSF版本替换。目录中可以看到不同的jar文件 - ${ServerLocation}/modules/system/layers/base/javax/faces/api/main，即jboss-jsf-api_2.2_spec-2.2.6.jar。

我通过在@ jamed中替换@ManagedBean和javax.faces.bean。*中的注释以及javax.enterprise.context中的注释来解决了这个问题。*。
