Why is <context: component-scan> not resolving Spring beans in OSGi Fragment package?

I am creating a Spring 3 application, JSF 2, OSGi (Virgo Tomcat 3.5.0.M03).

I currently have a host web and a set of fragments. The snippets package adds some .xhtml

JSF nodes (facelets) to the host. JSF pages in a fragment have their own UI controllers (Spring beans associated with a commandButton using the action attribute).

I have configured Spring beans with <context:component-scan base-package="my.scan.package" />

in a host (web application) package applicationContext.xml

.

Now, while it context:component-scan

works for the host (i.e. Spring beans acting as UI controllers), it doesn't work for the fragment:

javax.el.PropertyNotFoundException: /flow-deployer-db.xhtml @20,50 action="#{uiControllerDb.deployFlow()}": Target Unreachable, identifier 'uiControllerDb' resolved to null
    com.sun.faces.facelets.el.TagMethodExpression.invoke(TagMethodExpression.java:107)

      

        
        
        
      

    

So while the snippet has to be part of the same class as its host and the ui controller class is declared in that snippet as such:

package my.scan.package;
...
@Component("uiControllerDb")
public class UIControllerDb implements Serializable {

      

        
        
        
      

    

It cannot resolve the bean in the fragment (while running on the node node):

    <h:commandButton id="deployFlow" value="Deploy Flow" type="submit"
         action="#{uiControllerDb.deployFlow()}" />

      

        
        
        
      

    

Extract from package hosts MANIFEST.MF

...
Bundle-SymbolicName: web.host
Bundle-Version: 4.0.0.alpha
Require-Bundle: org.glassfish.com.sun.faces
Import-Package: javax.naming,javax.sql
Import-Bundle: org.eclipse.virgo.web.dm;version="[3.0.2.RELEASE,4)"
Import-Library: org.springframework.spring;version="[3.0,3.1.1)"
Bundle-Name: Web Host bundle
Web-ContextPath: /webHost

      

        
        
        
      

    

Excerpt from snippet MANIFEST.MF:

Bundle-SymbolicName: my.fragment.bundle
Bundle-Version: 4.0.0.alpha
Import-Library: org.springframework.spring;version="[3.0,3.1.1)"
Fragment-Host: web.host;bundle-version=4.0.0.alpha

      

        
        
        
      

    

How do I get JSF to resolve Spring beans in a fragment? Any pointers are appreciated. Thank.
