Bug 22551 Hierarchy pane missing "New..." menu item in context menu [type hierarchy]
(R2.0) I can almost use Eclipse like a Smalltalk Class Hierarchy browser. This is one of two problems. My custom perspective has a Packages pane, a Hierarchy pane (which includes methods of course) and a code editor pane. I cannot create a new class that is a subclass of the selected class in the Hierarchy pane. Note that I can do this in the "Types" pane from the context menu. The workaround is to use the Packages context menu, but this does NOT pick up the superclass that I have selected in the Hierarchy pane.

if (!element.exists()) {
						MessageDialog.openError(getSite().getShell(), TypeHierarchyMessages.getString("TypeHierarchyViewPart.error.title"), TypeHierarchyMessages.getString("TypeHierarchyViewPart.error.message")); 
						return;
					}
				}
			} else {
				int kind= element.getElementType();
				if (kind != IJavaElement.JAVA_PROJECT && kind != IJavaElement.PACKAGE_FRAGMENT_ROOT && kind != IJavaElement.PACKAGE_FRAGMENT) {
					element= null;
					JavaPlugin.logErrorMessage("Invalid type hierarchy input type.");
				}
			}
		}	
		if (element != null && !element.equals(fInputElement)) {
			addHistoryEntry(element);
		}
			
		updateInput(element);
	}
	
	/**
	 * Changes the input to a new type

	private void updateInput(IJavaElement inputElement) {
		IJavaElement prevInput= fInputElement;
		
		fInputElement= inputElement;
		if (fInputElement == null) {	
			clearInput();
