grid.getView（）。refreshNode（）：未定义视图

Question

我正在处理现有代码，但收到错误：

  

未捕获参考错误：未定义视图

在这一行：

grid.getView().refreshNode(store.indexOfId(record.data.UserId));

任何人都可以告诉我哪里可能是错误以及我如何解决它？ 我想要的只是更新网格的记录而不是整个网格

更多信息：

var grid= #{UsersGridPannel2};
var store = grid.getStore();
var recToUpdate = store.getById(record.data.UserId);

recToUpdate.set(record.getData());
recToUpdate.commit();                                    

grid.getView().refreshNode(store.indexOfId(record.data.UserId));

网格定义：
