我尝试使用以下代码选择/突出显示嵌套列表的一项：

var activelist= nestedList.getActiveItem();
var listselectednode = activelist.getNode(1);
nestedPanel.fireEvent('itemtap',activelist,1,listselectednode ,e);

但不起作用。

为了后代的利益，这里是您如何选择（突出显示）节点。这个答案改编自对该问题的评论。

var activeList = nestedList.getActiveItem();

// By index<br/>
activeList.getSelectionModel().select(index)

// By ID<br/>
var targetNode = activeList.store.getById(id);
activeList.getSelectionModel().select(targetNode);

以下是选择和点击节点的方法（按 ID）。

var activeList = nestedList.getActiveItem();
var targetNode = activeList.getNode(activeList.store.getById(targetNodeId));
var e = {} // You can provide event data here, if you like.

if (targetNode) {
  var targetIndex = activeList.indexOf(targetNode);

  nestedList.fireEvent('itemtap', activeList, targetIndex, targetNode , e);
  activeList.getSelectionModel().select(targetIndex, true);
}

For posterity's sake here is how you just select (highlight) a node. This answer was adapted from the comments on the question.

var activeList = nestedList.getActiveItem();

// By index<br/>
activeList.getSelectionModel().select(index)

// By ID<br/>
var targetNode = activeList.store.getById(id);
activeList.getSelectionModel().select(targetNode);

And here is how you select and tap a node (by ID).

var activeList = nestedList.getActiveItem();
var targetNode = activeList.getNode(activeList.store.getById(targetNodeId));
var e = {} // You can provide event data here, if you like.

if (targetNode) {
  var targetIndex = activeList.indexOf(targetNode);

  nestedList.fireEvent('itemtap', activeList, targetIndex, targetNode , e);
  activeList.getSelectionModel().select(targetIndex, true);
}
