在aikau中多次调用postCreate方法

Question

我们在分面搜索屏幕5.1+aikau(100.0.1)的Selected Items菜单中添加了一些自定义操作；

但是当我加载页面时，在自定义小部件中，postCreate方法调用了两次，当我选择“编辑属性”时，onSelectedDocumentsAction函数也调用了两次。

如果我在selectedItemsActionsGroup中再推入一个额外的项目，那么它就会调用这么多次(3次)。

var selectedItemsActionsGroup = widgetUtils.findObject(model.jsonModel.widgets,"id", "SELECTED_ITEMS_ACTIONS_GROUP");


    selectedItemsActionsGroup.config.widgets.push(
                    {
                        id : "OnActionEditProperties",
                        name : "faceted-search/CustomBulkSelectItems/CustomBulkSelectItems",
                        config : {
                            label : "Edit",
                            iconImage : url.context
                                    + "/res/components/documentlibrary/actions/y-16.png",
                            type : "action-link",
                            permission : "",
                            asset : "",
                            href : "",
                            hasAspect : "",
                            notAspect : "",
                            publishTopic : "BULK_OPS",
                            publishPayload : {
                                action : "onActionEditProperties",
                            }
                        }
                    },
                    {
                        id : "OnActionManaged",
                        name : "faceted-search/CustomBulkSelectItems/CustomBulkSelectItems",
                        config : {
                            label : "Managed",
                            iconImage : url.context
                                    + "/res/components/documentlibrary/actions/x-16.png",
                            type : "action-link",
                            permission : "",
                            asset : "",
                            href : "",
                            hasAspect : "",
                            notAspect : "",
                            publishTopic : "BULK_OPS",
                            publishPayload : {
                                action : "OnActionManaged",
                            }
                        }
                    });

Answer 1

我认为您两次调用相同的小部件faceted-search/CustomBulkSelectItems/CustomBulkSelectItems，publishTopic也从get.js文件中调用了两次。在get.js中更改小部件后，我觉得它看起来很好。

分享你的想法。

我像下面这样更改了你的东西，输出是这样的。

var selectedItemsActionsGroup = widgetUtils.findObject(model.jsonModel.widgets,"id", "SELECTED_ITEMS_ACTIONS_GROUP");

selectedItemsActionsGroup.config.widgets.push(
                    {
                        id : "OnActionEditProperties",
                        name : "faceted-search/CustomBulkSelectItems/CustomBulkSelectItems",
                        config : {
                            label : "Edit",
                            iconImage : url.context

更新的信息

请查看AlfFilteringMenuItem.js和

postCreate: function alfresco_menus_AlfFilteringMenuItem____postCreate() {
         this.filterTopic && this.alfSubscribe(this.filterTopic, lang.hitch(this, this.filter));
         this.inherited(arguments);
      },

和

filter: function alfresco_menus_AlfFilteringMenuItem__filter(payload) {
         this.alfLog("warn", "No implementation of filtering extension point", payload);
      }

没有找到具体的实现。如果启用调试日志，您应该能够看到警告消息。

我查看了aikau日志，您可以看到默认行为也具有与您的类似的多个请求(每个widger的每个请求)。唯一的区别是，filter方法和publish (lang.hitch)的东西。希望你现在清楚了。
