Property not found on type

Não estou entendendo o que acontece. Tenho definido um ContextBean. Segue o código:

@ManagedBean(name = "contextBean")
@SessionScoped
public class ContextBean {

	private Company company = null;
	private Client activeClient = null;
	
	
	public Company getCompany() {
		FacesContext context = FacesContext.getCurrentInstance();
		ExternalContext external = context.getExternalContext();
		String companyName = external.getRemoteUser();
		
		if (this.company == null || !companyName.equals(this.company.getName())) {
			if (companyName != null) {
				CompanyRN companyRN = new CompanyRN();
				this.company = companyRN.getCompanyByName(companyName);
				this.activeClient = null;
			}
		}
		
		return this.company;
	}
	
	public void setCompany(Company company) {
		this.company = company;
	}
	
	public Client getActiveClient() {
		return this.activeClient;
	}
	
	public void setActiveClient(ValueChangeEvent event) {
		Integer clientCode = Integer.parseInt((String)event.getNewValue());
		ClientRN clientRN = new ClientRN();
		this.activeClient = clientRN.get(clientCode);
	}
}

Estou usando Facelets. Se o meu header.xhtml está assim:

[code]<?xml version="1.0" encoding="UTF-8" ?>

<ui:composition>
	<h:form id="header">
	
		<h:outputLabel value="#{contextBean.company.longName}" />
		
		<h:outputLabel value="&nbsp;#{msg.client_active_client}:&nbsp;"/>
		
		<h:selectOneMenu valueChangeListener="#{contextBean.setActiveClient}" rendered="#{!empty contextBean}" onchange="submit()">
			<f:selectItem itemLabel="" noSelectionOption="true" />
			<f:selectItems value="#{clientBean.list}" var="client" itemValue="#{client.code}" itemLabel="#{client.longName}"/>
		</h:selectOneMenu>
		
		<h:outputLabel value="#{contextBean.activeClient.address}"/>
		
		<a href="#{request.contextPath}/j_spring_security_logout">Logout</a>
		
	</h:form>		
</ui:composition>
[/code]

Funciona perfeitamente, a página abre e eu posso navegar sem problemas. Porém, sempre que entro com uma parte de código COMENTADA, dá erro:

[code]<?xml version="1.0" encoding="UTF-8" ?>

<ui:composition>
	<h:form id="header">

		</h:selectOneMenu>
		
		<h:outputLabel value="#{contextBean.activeClient.address}"/>
		
		<a href="#{request.contextPath}/j_spring_security_logout">Logout</a>
