I'm getting the following exception on accessing an XHTML page on WildFly 8.1.0 final.

I do not use any CDI beans in the application (all of them are JSF managed beans).
The following is all irrelevant :
See the linked question instead.
EDIT :
Unfortunately, this happens, when OmniFaces (1.8.1) is added to the classpath along with PrimeFaces 5.1 final.
If OminFaces (1.8.1) alone is added (without PrimeFaces 5.1 final), then it causes the this exception to be thrown (the stacktrace is too long to accommodate in the question body).
The above mentioned exception happens (in the code snippet, not in the pastbin) in the following situation.
Given below a JSF managed bean as an example :
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;
}
}
Just accessing this bean as follows (from an XHTML page).
<?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>
This would throw the exception (if you happened to add OmniFaces (1.8.1 ) along with PrimeFaces (5.1.0 final) to the classpath).
The exception vanishes, when the given JSF managed bean is turned into a CDI bean as follows (works fine with or without OmniFaces (1.8.1), if it is a CDI bean).
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;
}
}
Finally, if <o:viewParam> is used on an XHTML page like as follows,
<ui:define name="metaData">
<f:metadata>
<o:viewParam name="id" value="#{bean.property}"/>
</f:metadata>
</ui:define>
then the following message appears on the server terminal. The name metaData is defined on the master page template just like as follows.
<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
On a blank project (without a master page template), if <o:viewParam> is used as follows.
<?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>
consider the above mentioned CDI bean with just an extra property id of type String, it throws the following exception.

Replacing <o:viewParam> by <f:viewParam> suppresses the above exception.
I do not know, if this may work on a higher version of JSF, since I still do not know how to change a JSF version in WildFly (8.1.0 final) (it uses JSF 2.2.6 as default). Unlike GlassFish, there is no javax.faces.jar file I can see somewhere in a server directory that can be replaced with a newer JSF version. A different jar file is seen in the directory - ${ServerLocation}/modules/system/layers/base/javax/faces/api/main which is jboss-jsf-api_2.2_spec-2.2.6.jar.

I solved this issue by replacing @ManagedBean and annotations in javax.faces.bean.* by @Named and annotations in javax.enterprise.context.*.
