推荐答案

tree小部件支持大量高级操作.问题是顶点团队从未将这些选项提供给开发人员.相反，他们选择模仿用于老树的技术.虽然那棵树还提供了比他们所暴露的更多的东西...
简而言之，对于这两个版本，传递到树的数据都是页面渲染中的json-payload.树将消耗掉它并渲染节点.由于其数据的静态"性质，因此无法刷新它.

The short of it is that with both versions the data delivered to the tree is a json-payload in the render of the page. The tree consumes this and renders the nodes. Because of the "static" nature of its data it can not be refreshed.

长话短说:对不起，由apex生成的树不支持刷新.您需要重新加载页面.

Long story short: sorry, the tree as generated by apex does not support refreshing. You'll need to reload the page.
