Problem with viewscoped CDI bean

[mirko.antic]

I have problem using viewscoped CDI beans.
@PreDestroy method in bean has been never called.
I never had similar problem before using @ManagedBean instead @Named.
After few clicking and opening viewscope pages I am getting error like this:

javax.servlet.ServletException
javax.faces.webapp.FacesServlet.executeLifecyle(FacesServlet.java:725)
javax.faces.webapp.FacesServlet.service(FacesServlet.java:451)
com.crmfo.filter.CharacterEncodingFilter.doFilter(CharacterEncodingFilter.java:32)
org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:53)
com.crmfo.filter.AdministracijaFilter.doFilter(AdministracijaFilter.java:44)

java.lang.NullPointerException
com.sun.faces.application.view.ViewScopeContextManager.destroyBeans(ViewScopeContextManager.java:150)
com.sun.faces.application.view.ViewScopeContextManager.clear(ViewScopeContextManager.java:101)
com.sun.faces.application.view.ViewScopeManager.removeEldestViewMap(ViewScopeManager.java:376)
....

Please help

I believe @ManagedBean was deprecated (Jarkara 10.x)

To help yourself why not display the versions used. Use "View profile".

@ManagedBeans shouldn't be used anymore since JavaEE6. That being said, it would be easier for us to help if you could know the configuration they use.
Glassfish, payara, tomcat, ...? Which JavaEE version? Which operating system? Unfortunately we don't have a crystal ball here.
