我正在尝试构建一个清单应用程序，其中清单由许多部分组成，每个部分由许多任务组成。 我正在使用Nativescript UI-dataform来呈现表单，因为这些表单是由REST API动态生成的JSON模型。 我创建了一个分页器，用于在当前活动 JSON 模型的模板中设置上一个或下一个任务，并在数据表单的 [源和 [元数据输入。 当我点击上一个或下一个 V 形时，视图会按预期更改，并且数据表单会更新。 当我向前移动至少两个任务，然后点击左 V 形(上一个任务页面图标)时，似乎会出现问题。 然后，由于某种原因，表单在文本编辑器中显示任务，而不是在元数据模型上显式设置的开关，然后我收到以下错误。 我的代码低于错误。 知道这里可能出了什么问题/我该如何解决这个问题吗？ 我已经尝试了所有其他方法，但没有任何成功，并且在进行Google搜索时看不到任何相关内容... 从错误来看，问题似乎是 rad dataform 尝试使用应该使用布尔开关编辑器的文本编辑器？

所以事实证明，当我在控制器中更改"任务"索引时，Rad Dataform 选择了表单源的更改，但没有选择元数据的更改...... 我为解决此问题所做的是：每当我导航到上一个/下一个任务时，手动设置表单元数据......
