bundles/org.eclipse.ui.views.properties.tabbed/src/org/eclipse/ui/internal/views/properties/tabbed/view/OverridableTabListContentProvider.java
IStructuredSelection selectionFromList = (IStructuredSelection) tabbedPropertyViewer
				.getSelection();
		if (!selectionFromList.equals(StructuredSelection.EMPTY)) {
			currentSelectedTabInList = (TabDescriptor) selectionFromList
					.getFirstElement();
		}
		AbstractOverridableTabListPropertySection section = getOverridableTabListPropertySection();
		if (section == null) {
			if (currentSelectedTabInList == null) {
				/*
				 * make sure there is a selected tab in the list.
				 */
				TabDescriptor newSelectedTab = (TabDescriptor) tabbedPropertyViewer
						.getElementAt(0);
				if (newSelectedTab != null) {
					tabbedPropertyViewer.setSelection(new StructuredSelection(
							newSelectedTab), true);
				}
			}
			return;
		}
		ITabItem[] dynamicTabItems = section.getTabs();
		if (dynamicTabItems == null) {
			/*
			 * if the section does not provide overridden tabs, return.
