Question

我有一个choicelist initializer，允许用户选择＆＃39; image＆＃39;或者＆＃39;视频＆＃39;。我需要那个：

如果＆＃39;视频＆＃39;选择了类型，应用mixin umix:video
如果＆＃39;图片＆＃39;选择了类型，应用mixins umix:image 和 umix:link

有可能吗？

以下是我所拥有的最小示例（问题在代码中作为注释）：

definitions.cnd ：

[unt:homeHeader] > jnt:content
 - type (string, choicelist[homeHeaderTypeListInitializer,resourceBundle]) = 'image' mandatory autocreated nofulltext

[umix:video] > jmix:templateMixin mixin
 extends = unt:homeHeader
 - video (weakreference, picker[type='video'])  i18n mandatory < jnt:file

[umix:image] > jmix:templateMixin mixin
 extends = unt:homeHeader
 - image (weakreference, picker[type='image'])  i18n mandatory < jnt:file

[umix:link] > jmix:templateMixin mixin
 extends = unt:homeHeader
 - title (string) i18n < '^.{1,255}$'
 - url (string) = 'https://' i18n mandatory indexed=no

homeHeaderTypeListInitializer.java ：

public List<ChoiceListValue> getChoiceListValues(ExtendedPropertyDefinition epd, String param, List<ChoiceListValue> values, Locale locale, Map<String, Object> context) {
        List<ChoiceListValue> myChoiceList = new ArrayList<>();

        if (context == null) {
            return myChoiceList;
        }
        HashMap<String, Object> myPropertiesMap;

        myPropertiesMap = new HashMap<>();
        myPropertiesMap.put("addMixin", "umix:image");
        // HOW CAN I ADD THE SECOND MIXIN umix:link HERE ?
        myChoiceList.add(new ChoiceListValue("image", myPropertiesMap, new ValueImpl("image", PropertyType.STRING, false)));

        myPropertiesMap = new HashMap<>();
        myPropertiesMap.put("addMixin", "umix:video");
        myChoiceList.add(new ChoiceListValue("video", myPropertiesMap, new ValueImpl("video", PropertyType.STRING, false)));

        return myChoiceList;
    }

我知道我可以使用umix:image和umix:link等所有属性制作单个mixin，但我想知道是否有任何选项可以避免这种情况。

作为一种解决方法，您是否在cnd文件中尝试过类似的内容？这个想法是添加一个新的umix：videoimage嵌入了许多mixins。也许这会解决你的问题......

[umix:videoMix] mixin
 - video (weakreference, picker[type='video'])  i18n mandatory < jnt:file

[umix:imageMix] mixin
 - image (weakreference, picker[type='image'])  i18n mandatory < jnt:file


[umix:video] > umix:templateMixin,umix:videoMix mixin
 extends = unt:homeHeader

[umix:image] > umix:templateMixin,umix:imageMix mixin
 extends = unt:homeHeader

[umix:videoimage] > umix:templateMixin,umix:videoMix,umix:imageMix mixin
 extends = unt:homeHeader
