使用 dialog 给外部表单设置数据时候, 数组设置空数据时会遇到报错 [mobx-state-tree] You are trying to read or write to an object that is no longer part of a state tree. (Object type: 'FormStore', Path upon death: '', Subpath: '', Action: '.setCurrentAction()'). Either detach nodes first, or don't use objects after removing / replacing them in the tree.

外部表格渲染的数据会同时显示在 dialog 第一次打开时.

但, 当打开 dialog, 并清空数组, 点击 确认 按钮, 会遇到报错

[mobx-state-tree] You are trying to read or write to an object that is no longer part of a state tree. (Object type: 'FormStore', Path upon death: '', Subpath: '', Action: '.setCurrentAction()'). Either detach nodes first, or don't use objects after removing / replacing them in the tree.

不过外部数据可以正常清空.

暂时实验后可以通过 form 表单包裹一下解决.
即 dialog 的 body 内容设置为

{"type": "form", "body": [
                                                    {"type": "input-array", "name": "tDItems", "label": "tDItems",
                                                        "items": [
                                                            {"type": "combo", "controls": [
                                                                    {"label": "name", "name": "name", "type": "input-text"},
                                                                    {"label": "age", "name": "age", "type": "input-text"},
                                                                    {"label": "addr", "name": "addr", "type": "input-text"},
                                                                ],
                                                            },
                                                        ],
                                                    },
                                                ]},

就是样式可能需要再额外自行调整一下
