p:commandButton not invoking action

Question

I've got a p:commandButton in a simple login form. The action is not firing. I've verified that the controller and function exist, checked for nested f:forms, enclosed everything in f:view, removed validation requirements, but the action doesn't fire.

The action listener just sets the login flag and then the page refreshes with new rendering. If I reference the listener function directly, it fires, but not from the commandButton.

Here's the controller bean:

@ManagedBean(name = "uiController")
@SessionScoped
public class UiController implements Serializable {

private Boolean isLoggedIn;
private String userName;
private String password;

public UiController() {
    isLoggedIn = false;
}

public String getUserName() {
    return userName;
}

public void setUserName(String userName) {
    this.userName = userName;
}

public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

public Boolean getIsLoggedIn() {
    return isLoggedIn;
}

public String getLoginLogoTopLine() {
    return "Yoyodyne";
}

public String getLoginLogoBottomLine() {
    return "Corporation";
}

public void login() {
    isLoggedIn = true;
}

}

Here's the html:

    <h:outputStylesheet library="css" name="transend-ui.css"/>

UPDATE

OK sorry for posting snippets in the comments. I usually work things out for myself. This is the first time I've had to ask for help and I'm not familiar with posting. Not a newb at Java, definitely a newb at this.

Here's what I now have for html:

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:f="http://xmlns.jcp.org/jsf/core"
      xmlns:p="http://primefaces.org/ui">
    <h:head>
    </h:head>
    <h:body id="enchilada">
        <f:view>
            <h:form id="LoginForm">
                <p:commandButton action="#{uiController.login}" value="login"/>
            </h:form>
        </f:view>
    </h:body>

</html>

Here's the bean:

@ManagedBean(name = "uiController")
  @SessionScoped
  public class UiController implements Serializable {

    public void login() {
        System.out.println("login invoked");
    }
}

There may be a problem with your namespace declarations. You have used:

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:f="http://xmlns.jcp.org/jsf/core"
      xmlns:p="http://primefaces.org/ui">

Replace the above with:

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:p="http://primefaces.org/ui"
      xmlns:f="http://java.sun.com/jsf/core">

To be honest, I'm not familiar with how these namespace declarations work, so I don't know if or why this would make a difference. I would have put this in a comment, but it's too long.
