Why is my JSF FacletContext==null?

Question

My FaceletContext I try to get with

FaceletContext faceletContext = (FaceletContext) context.getAttributes().get(FaceletContext.FACELET_CONTEXT_KEY);

is always null. What is going wrong here?

Actually what I try to do is to add a composite component dynamically from bean.

Update:

To be more clear. I have the following bean:

@Named
@SessionScoped
public class GroupComponentTreeBuilder implements Serializable {

public UIComponent getGroupTree() {

    UIComponent parent1 = UIComponent.getCurrentComponent(FacesContext.getCurrentInstance());

    return includeCompositeComponent(parent1, "group", "elementgroup.xhtml", "myNewSuperId");
}

public static UIComponent includeCompositeComponent(UIComponent parent, String libraryName, String resourceName, String id) {
    FacesContext context = Faces.getContext();
    Application application = context.getApplication();

    FaceletContext faceletContext = Faces.getFaceletContext();

    Resource resource = application.getResourceHandler().createResource(resourceName, libraryName);
    UIComponent composite = application.createComponent(context, resource);
    composite.setId(id);

    UIComponent implementation = application.createComponent(UIPanel.COMPONENT_TYPE);
    implementation.setRendererType("javax.faces.Group");
    composite.getFacets().put(UIComponent.COMPOSITE_FACET_NAME, implementation);

    parent.getChildren().add(composite);
    parent.pushComponentToEL(context, composite); // This makes #{cc}
                                                    // available.
    try {
        faceletContext.includeFacelet(implementation, resource.getURL());
    } catch (IOException e) {
        throw new FacesException(e);
    } finally {
        parent.popComponentFromEL(context);
    }

    return composite;
}
}

And I want to bind the loaded bean to a panelGroup :

<ui:fragment>
    <h:panelGroup binding="#{groupComponentTreeBuilder.groupTree}" />
</ui:fragment>

The problem is that the FacletContext is null, so i can not call includerFacelet ().

Any suggestions?

Im using JSF 2.2.0 I tried setting javax.faces.PARTIAL_STATE_SAVING in web.xml to false. I still get null. — flosk8, Jul 22 '13 at 09:51
It would be helpful if you could give an example on how and where (in the jsf lifesycle) I can access the FacletContext. — flosk8, Jul 22 '13 at 10:26

The problem was that

FaceletContext.FACELET_CONTEXT_KEY

returned the wrong String key "com.sun.faces.facelets.FACELET_CONTEXT"

but I needed

javax.faces.FACELET_CONTEXT

Thanx Mat :-)
