Extending AR_SRVC_NEWS (Problem: extension works only on 2nd start of newsFeedList)

Hi everyone,

In the FIORI launchpad, after clicking a news tile I want the feeds to be displayed in a simple list with no links to the underlying feed. I therefore implemented an extension to the standard FIORI app AR_SRVC_NEWS where i changed the list mode of the "newsfeed"-element.

Extension code looks like this (NewsTileDrillDownCustom.controller.js):

onBeforeRendering: function() {
    var newsList = this.getView().byId("newsList");

I then set a target mapping to the extension service in Launchpad Designer.

Target mapping looks like this:

semantic object: 'NewsFeed';
action: 'displayNewsList';
Type: 'Ui5-app';
URL: '/sap/bc/ui5_ui5/sap/zar_srvs_news/';
ID: 'WebContent.AR_SRVC_NEWSExtension'

My problem is, the extension works well, but only on the second click on the news tile. The first click after logging in to the launchpad triggers a call for the original AR_SRVC_NEWS (with the List being of mode "sap.m.ListMode.SingleSelectMaster"). Only after leaving the news feed and another click on the tile my extension ZAR_SRVC_NEWS service is called.

My extension code is placed in the 'onBeforeRendering' event handler. I´ve already tried putting it into "onInit" and "onAfterRendering" - No success.

    Just in case someone faces a similar question.

    I did not find a solution to make my extension work from the start. Instead I implemented a workaround.

    I just copied every file of the original AR_SRVC_NEWS app from the SAP repository to a new UI5 app and changed the view according to my needs. Then I made the target mapping point to my new service URL and component ID.

    Although I´d have prefered the extension as a leaner solution, clother to the SAP standard, this approach at least gets the job done.

    Hi Michael,

    I did not change that much if i remember correctly.

    Regarding the app, in the NewTileDrillDown.view.js we´ve changed the "oNewsItemTemplate" to a sap.m.FeedListItem.

    The target mapping in fiori designer then points to

    semObj: "NewsFeed"

    action: "displayNewsList"

    url: /sap/bc/ui5_ui5/sap/z_simplenewsf/ (with z_simplenewsf being the copied app´s name)

    id: WebContent

    • Hi Jens,

      i tried to do this, but when i only update the application name, there coming up two error's:

      1. When trying to deploy the adjusted app, there comes a prompt which tells me, that it's forbidden to override/delete sap textelements.

      ( --> I found out, that this has something to do with the properties-files for the tiles configuration, so I deleted them )

      2. After the deletion of the properties-files, I could deploy the app. As soon as I deployed the app, there came another prompt which was telling me, that there are now two applications with the same ID (the orginial and my copy of it). I just ignored that fact, but even though I adjusted the target mapping to my z-url, the original app has been called. Then I deactivated the original app in the sicf transaction but after that, the tile in the launchpad wasn't working at all anymore. Finally I gave up..

      How did you handle this?

      Best regards,
