Target Unreachable, identifier resolved to null - JSF

Problem similar to: Target Unreachable, identifier resolved to null JSF 2.2 How to reference JSF managed beans which are provided in a JAR file? Identifying and solving javax.el.PropertyNotFoundException: Target Unreachable Java EE 6: Target Unreachable, identifier 'helloBean' resolved to null

But none of resolutions helped me. When I click command button (on page, please see xhtml file) I got:

An Error Occurred:
javax.el.PropertyNotFoundException: /navigate.xhtml @15,90 action="#{navigator.choosePage}": Target Unreachable, identifier 'navigator' resolved to null

I can get why. Why this bean is not visible in jsf?

Using java8, j2ee 7, tomcat 6.0.44

As @BalusC said in comment. Problem was in tomcat 6. Had to upgrade to newer version of tomcat - 8. Many kudos.
