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]
    });
  });
},

async handleChangePower(row) {
  this.power = true;
  await this.getRolePermisson03();

  this.roleForm.roleId = row.id;

  await this.getRolePermisson04();
  this.dialogFormVisiblePower = true; 
},

getRolePermisson04() {
  getPermissionIds(this.roleForm).then(res => {
    console.log("角色权限", res);
    this.$nextTick(() => {
      this.checkedCities = res.data.data;
      this.dialogFormVisiblePower = true; 
    });
  });
},
