前端 - element的tree树回显问题？

Question

第一次获取数据不会回显,第二次才会回显
两个接口 第一个是获取所有的权限的,第二个是获取已有权限的

我第二次获取才会回显

搞一天了 也没找出来原因.....

主要代码：

async handleChangePower(row) {  this.power = true;  await this.getRolePermisson03();  // this.getRolePermisson03()  this.roleForm.roleId = row.id;  await this.getRolePermisson04();  this.dialogFormVisiblePower = true;},getRolePermisson03() {  getPermissionTree().then(res => {    console.log("获取所有权限111", res);    this.cities = res.data.data;  });},

getRolePermisson04() {  getPermissionIds(this.roleForm).then(res => {    console.log("角色权限", res);    this.$nextTick(() => {      this.checkedCities = res.data.data;        // 数据格式[1,2,3]    });  });},
