Eclipse RCP Question

Does anyone have experience with Eclipse RCP.  I am working through the
eclipse RCP Platform book by McAffer and Lemieux.  I am doing this in
parallel between the Eclipse 3.1 install provided by the book and my
normal Eclipse 3.2 environment.  I am having trouble getting it to bring
up the view in my Eclipse 3.2 environment.   Instead of a treeviewer I
just see a blank.

After carefully comparing the code, I decided just to try to trace the
execution.  It turns out that class I defined for my view is never
instantiated in my Eclipse 3.2 environment but the constructor and the
createPartControl is executed prior to bringing up the application.
Note that plugin.xml has:
   <extension
         point="org.eclipse.ui.views">
      <view
            class="org.eclipsercp.hyperbola.ContactsView"
            icon="icons/groups.gif"
            id="org.eclipsercp.hyperbola.views.contacts"
            name="Contacts"/>
   </extension>

Also the class ContactsView does exist, but like I said breakpoints in
the contructor and on the first line of createPartControl are never hit.

	public ContactsView() {
		super();
	}
	/*
	 * The content provider class is responsible for
	 * providing objects to the view. It can wrap
	 * existing objects in adapters or simply return
	 * objects as-is. These objects may be sensitive
	 * to the current input of the view, or ignore
	 * it and always show the same content 
	 * (like Task List, for example).
	 */
	 
	class ViewContentProvider implements IStructuredContentProvider
{
		public void inputChanged(Viewer v, Object oldInput,
Object newInput) {
		}
		public void dispose() {
		}
		public Object[] getElements(Object parent) {
			return new String[] { "One", "Two", "Three" };
		}
	}
	
	/**
	 * This is a callback that will allow us
	 * to create the viewer and initialize it.
	 */
	public void createPartControl(Composite parent) {
		initializeSession();  // temporary tweak to build a fake
model
		treeViewer = new TableViewer(parent, SWT.MULTI |
SWT.H_SCROLL | SWT.V_SCROLL);
		getSite().setSelectionProvider(treeViewer);
		treeViewer.setLabelProvider(new
WorkbenchLabelProvider());
		treeViewer.setContentProvider(new
BaseWorkbenchContentProvider());
		treeViewer.setInput(session.getRoot());
		session.getRoot().addContactsListener(new
IContactsListener() {
			public void contactsChanged(ContactsGroup
contacts, ContactsEntry entry){
				treeViewer.refresh();
			}
		});
		//treeViewer.setSorter(new NameSorter());
		
		//makeActions();
		//hookContextMenu();
		//hookDoubleClickAction();
		//contributeToActionBars();
	}
