Using more than one <f:viewParam .. /> in <f:metadata .. causes error
Question
I want to parse two parameters from the URL but when I include two f:viewParam in header of page i get an error: The metadata component needs to be nested within af:metadata tag. Suggestion: enclose the necessary components within f:metadata
An example of a URL: http://domain.com?email=blah@dom.com&key=4793e258-518f-432d-9af2-8d639a13757d
I'm using JSF 2.2.6 and I tried swapping the name space (below) from xmlns.jcp.org to java.sun.com but that made no difference.
My simplified page is:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<f:view>
<h:head>
<f:metadata>
<f:viewParam name="email" value="#{credentialsBacking.returnedEmail}"/>
<f:viewParam name="key" value="#{credentialsBacking.returnedActivationKey}"/>
</f:metadata>
</h:head>
<h:body>
</h:body>
</f:view>
</html>
Thanks

Well, I don't know why, but I recreated the project from scratch and the issue went away. Curiously I had to use the name space of xmlns:f="http://java.sun.com/jsf/core" instead of xmlns:f="http://xmlns.jcp.org/jsf/core" to get the parameters to save to the bean.

This works for me with no problem in Mojarra 2.2.6 and Tomcat 7:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:f="http://xmlns.jcp.org/jsf/core">
<f:view>
<h:head>
<f:metadata>
<f:viewParam name="email" />
<f:viewParam name="key" />
</f:metadata>
</h:head>
<h:body>
#{email} - #{key}
</h:body>
</f:view>
</html>
Also this one does:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:f="http://xmlns.jcp.org/jsf/core">
<f:view>
<h:head>
<f:metadata>
<f:viewParam name="email" value="#{bean1.email}" />
<f:viewParam name="key" value="#{bean1.key}" />
</f:metadata>
</h:head>
<h:body>
#{bean1.email} - #{bean1.key}
</h:body>
</f:view>
</html>
@ManagedBean
@ViewScoped
public class Bean1 {
public Bean1() {
System.out.println("Bean created");
}
private String email;
private String key;
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
System.out.println(email);
}
public String getKey() {
return key;
}
public void setKey(String key) {
this.key = key;
System.out.println(key);
}
}
It doesn't matter where I place the <f:metadata /> inside the <html /> , parameters are properly set.
Having seen your last comments, the issue seems to be related with your development tool not properly deploying resources to the server . Clean up your workspace and check the proper content is being copied.
