我试过其他 TransformerClass，例如：
DelegatingMultiValueFieldTransformer
DelegatingCompositeFieldTransformer
但我什么也得不到。
请问有什么帮助吗？
您需要将此 "transformerClass" 添加到 SwitchableFieldDefinition 高度。
希望能解决您的问题。
我在部署我的组件的对话框时遇到问题，它属于 class SwitchableFieldDefinition，它有一个包含 MultiValueFieldDefinition 的选项并且它有一个嵌套的 CompositeFieldDefinition:
这是我部署此对话框时的日志错误：

我试过其他 TransformerClass，例如：
DelegatingMultiValueFieldTransformer
DelegatingCompositeFieldTransformer
但我什么也得不到。 请问有什么帮助吗？
您需要将此 "transformerClass" 添加到 SwitchableFieldDefinition 高度。
希望能解决您的问题。
