selectcomponent 返回null

AI助手支持GPT4.0

Framework type problem type terminal type wechat version basic library version applet bug wechat Android client 7.0.17 2.12.0 I have a custom component named naid index.wxml In, there are four naid nodes, each with a different ID. when I look at the node tree, I can see the, ID is different, but this.selectcomponent Only three of them can be found, and the remaining one always returns null. It is not a necessary problem, but every time it appears, it is almost the same phenomenon, except that sometimes it is the first naid node, sometimes it is the second node, sometimes it is the third node, and sometimes it is the fourth one
