我做错了什么？对于XML模型，路径中不能包含根。您应该从绑定路径中删除所记录的/Rowsets 所以这条路应该是
rows="{path:'/Rowset/Row/root', parameters: {arrayNames:['/children']}}"
<children>
<id>01</id>
<level>01</level>
<name>Case Packer</name>
<children>
<id>0101</id>
<level>0101</level>
<name>Unscheduled</name>
</children>
</children>
01
01
封隔器
0101
0101
计划外
上文中，该模型将考虑根子节点有4个子节点。要解决这个问题，id、level和name应该是子对象的属性
所以您的treedata.xml应该是这样的<?xml version="1.0" encoding="utf-8"?>
