Bug 264796 [TabbedProperties] HockeyLeagueExample needs EMF source code regenerated
I discovered when looking into another problem that the EMF source code for the Hockey League Example has not been regenerated for a while.
examples/org.eclipse.ui.examples.views.properties.tabbed.hockeyleague/src/org/eclipse/ui/examples/views/properties/tabbed/hockeyleague/ui/editor/HockeyleagueEditor.java
* @return the new property sheet page.
	 */
	public TabbedPropertySheetPage getPropertySheetPage() {
		if (propertySheetPage == null || propertySheetPage.getControl() == null) {
			propertySheetPage = new HockeyleaguePropertySheetPage(this);
		}
		return propertySheetPage;
	}
	/**
	 * This deals with how we want selection in the outliner to affect the other
	 * views. <!-- begin-user-doc --> <!-- end-user-doc -->

	public void handleContentOutlineSelection(ISelection selection) {
		if (currentViewerPane != null && !selection.isEmpty()
			&& selection instanceof IStructuredSelection) {
			Iterator selectedElements = ((IStructuredSelection) selection)
				.iterator();
			if (selectedElements.hasNext()) {
				
				
				Object selectedElement = selectedElements.next();
				ArrayList selectionList = new ArrayList();
				selectionList.add(selectedElement);
				while (selectedElements.hasNext()) {
					selectionList.add(selectedElements.next());
				}
