Question

希望你有时间帮助我。在任何情况下，我的Magento 2数组映射都不会将selected =“selected”写入我的字段。为此疯狂。数据将被保存并正确获取。

非常感谢你的帮助。

我看到您已经用数据重新加载了所有需要的方法，但是在 Sumedia \ Switcher \ Block \ Adminhtml \ System \ Config \ Form \中的 getRenderer 方法中存在问题在Field \ Groupmap 类中，尝试将'is_renderer_to_js_template'更改为'is_renderer_to_js_template'

几天前，在开发自定义模块期间遇到了相同的问题，并且仅在查看了magento的核心代码（目录库存模块的代码）=）后才找到解决方案
