postCreate method calling multiple times in aikau

Question

We are adding some custom actions in Selected Items menu in Faceted search screen 5.1+aikau(100.0.1);

but when i load the page,In Custom widget postCreate method is calling twice and when i select 'Edit properties' then also onSelectedDocumentsAction function calling twice.

if i push one more extra item in selectedItemsActionsGroup then that many times(3 times) its calling.

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",

In which file, you've added the `var selectedItemsActionsGroup ....` code ? — Muralidharan Deenathayalan, Mar 14 '17 at 10:16
Cannot read property "widgets" from null . I'm getting this error after adding your code in faceted-search.get.js (web-extension folder). — Muralidharan Deenathayalan, Mar 14 '17 at 13:03
you need to add "dijit/_WidgetBase" in define in custom widget. — user739115, Mar 14 '17 at 13:20
I have added above code in faceted-search.get.js file but actions are not showing.Could help me to show actions? — Sanjay, Mar 24 '20 at 04:52

I think you're calling same widget faceted-search/CustomBulkSelectItems/CustomBulkSelectItems twice and publishTopic also called twice from the get.js file. After change the widget in the get.js it is looking fine to me.

Share your thoughts.

I changed your something like below and the output is like that.

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",

Updated info

Please look at the AlfFilteringMenuItem.js and

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

and

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

There is no specific implemenation is found. If you enable debug logs, you should be able to the warn messages.

I looked at the aikau logs and you can see the default behaviour also having muliple requests( each request for each widger) similar to yours. The only difference is , filter method and publish (lang.hitch) stuffs. Hope you're clear now.

If you see the OOB faceted-search.get.js ,they have used same name as "alfresco/documentlibrary/AlfDocumentActionMenuItem" and topic as 'ALF_SELECTED_DOCUMENTS_ACTION_REQUEST' for multiple actions(Copy To,Move To,Download as Zip,Start Workflow etc).For my custom actions I don't think It will be a good logic if we create new files for every custom action. — user739115, Mar 14 '17 at 13:41
Thanks for pointing out and you're correct. Let me check the OOB stuffs and will update you. — Muralidharan Deenathayalan, Mar 14 '17 at 14:41
I updated the answer (**Updated info**), please take a look. — Muralidharan Deenathayalan, Mar 14 '17 at 16:57
so you mean its existing behaviour and whatever logic I have written is correct.In that case Can I use same Name 'name : "faceted-search/CustomBulkSelectItems/CustomBulkSelectItems" and publishTopic : "BULK_OPS" for our multiple custom actions? ' — user739115, Mar 15 '17 at 06:27
Yes, but it will trigger the event multiple times. Do you really publishTopic there.. I would recommend debug more for the deleteaction to understand how the publishtopic is handled in Aikau. — Muralidharan Deenathayalan, Mar 15 '17 at 06:30
If I dont mention the publishTopic then How come our custom method[onSelectedDocumentsAction] will be called?.publishTopic is subscribed in postCreate method so that our method[onSelectedDocumentsAction] will be called.Do you see anything wrong? — user739115, Mar 15 '17 at 06:43
