Bug 184755 [DataBinding] internal tree content provider does not work
I broke the tree content providers while trying to update them to use TreePaths. It would be good to have a working implementation again...

        if (!shouldHavePendingNode && hasPendingNode) {
            hasPendingNode = shouldHavePendingNode;
            contentProvider.remove(treePath, Collections.singleton(contentProvider.getPendingNode()), true);
        }
        
        updateStale();
    }
    /**
     * @return the element
     */
    public Object getElement() {
        return treePath;
    }
    /**

     */
    public void prefetch() {
        Set children = getChildren();
        if (!children.isEmpty()) {
            contentProvider.add(treePath, children);
        } else {
            
            contentProvider.getViewer().refresh(treePath);
        }
    }
