I am trying to use setValue in an integration test to set a value of an injected object that comes from the selection in a drop down menu, but when I debug the test, the value is always null.

Here is my component

@Name("directoryHome")
public class DirectoryHome extends EntityHome<Directory> {
    
    /* Persistence Accounting Fields */
    /** @see java.io.Serializable */
    private static final long serialVersionUID = -7944607543874301481L;
    
    /* DirectoryHome Fields */
    /** Unique identifier for Directory. */
    @RequestParameter 
    private Long directoryId;
    /** Directory to which this Directory should move all its contents to before being removed. */
    @In(required = false)
    @Out(required = false)
    private Directory directoryToMoveTo;
    /* Java/Seam Persistence API Method Overrides */
    /** @return Directory */
    @Override
    @Factory("directory")
    public Directory getInstance() {
        return super.getInstance();
    }
    /** @return list of Directory objects that the contents of a directory can be moved to before being removed. */
    @DataModel(value = "directories")
    public List<Directory> getDirectories() {
        return getEntityManager().createQuery("from Directory directory where directory.id != #{directory.id}").getResultList();
    }
    /**
     * @see org.jboss.seam.framework.Home.getId()
     * @return Id of Directory
     */
    @Override
    public Object getId() { 
        if (directoryId == null) {
            return super.getId();
        } else {
            return directoryId;
        }
    }
    /** 
     * Remove the directory after removing it from the repository.
     * @return Result String
     */
    @Override
    public String remove() {
        String result = "error";
        Directory directory = getInstance();
        if (directoryToMoveTo != null) {
            for (Document d : getInstance().getDocuments()) {
                d.setComments(d.getComments() + "\nMoved to " + directoryToMoveTo.getName() + " on " + new Date().toString());
            }
            directoryToMoveTo.addAllDocumentsFromDirectory(directory);
        }
        result = super.remove();
        return result;
    }

and the test method

    @Test
    public void testRemoveWithCopyDirectory() throws Exception {
        login();
        new SmartFacesRequest("/directoryRemove.xhtml") {
            @Override
            protected void applyRequestValues() throws Exception {
                super.applyRequestValues();
                setParameter("directoryId", "1");
            }
            protected void updateModelValues() throws Exception {
                super.updateModelValues();
                DirectoryHome directoryHome = (DirectoryHome) getValue("#{directoryHome}");
                assert directoryHome != null;
                EntityManager em = (EntityManager) getValue("#{entityManager}");
                Directory dir = em.find(Directory.class, 2L);
                setValue("#{directoryToMoveTo}", dir);
            }
            @Override
            protected void invokeApplication() throws Exception {
                super.invokeApplication();
                assert invokeMethod("#{directoryHome.remove}").equals("removed");
            }
        }
        .run();

and finally the xhtml

<h:selectOneMenu id="directoryToMoveTo" value="#{directoryToMoveTo}">
   <s:selectItems var="_directory" value="#{directories}" label="#{_directory.name}" noSelectionLabel="None"/>
   <s:convertEntity />
</h:selectOneMenu>

any help is appreciated.
