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.

setSelection(new StructuredSelection(elementToSelect), true);

				setSelection(StructuredSelection.EMPTY, true);
				fPreviousSelectedElement= StructuredSelection.EMPTY;
			}
			fPreviousSelectionProvider= part;
			return;
		}
		
		
		if (part != fPreviousSelectionProvider && selectedElement != null && !selectedElement.equals(currentInput) && isInputResetBy(selectedElement, currentInput, part)) {
			if (!isAncestorOf(selectedElement, currentInput))
				setInput(null);
			fPreviousSelectionProvider= part;
			return;
		} else	if (selection.isEmpty() && !isInputResetBy(part)) {
			fPreviousSelectionProvider= part;

			setInput(null);
