Spring: @PostConstruct is not called

Question

Class A:

package myproject.web.factory.components;

@Component
public class AppComponentFactory{
}

Class B

package myproject.web.components;
import myproject.web.factory.components.AppComponentFactory;

@Component
public class AdminTabSheet{

   @Autowired
   private AppComponentFactory appComponentFactory;

   public AdminTabSheet() {
   }

   @PostConstruct
   public void init() {
      // does something with appComponentFactory
   }
}

Configuration XML:

<context:component-scan base-package="myproject.spring" />

WebConfig.java:

package myproject.spring.config;

@Configuration
@ComponentScan(basePackages = { "myproject.web.components"})
public class WebConfig {

I have followed all the rules in http://docs.oracle.com/javaee/5/api/javax/annotation/PostConstruct.html:

Only one method can be annotated with this annotation.
The method MUST NOT have any parameters except in the case of EJB interceptors
The return type of the method MUST be void.
The method MUST NOT throw a checked exception.
The method on which PostConstruct is applied MAY be public, protected, package private or private.
The method MUST NOT be static .

Any ideas?

If there was no typo, I believe the correct would be

@ComponentScan(basePackages = { "myproject.web"})

since AppComponentFactory is in myproject.web.factory package.
