Enigma.js : No "change" event on a bookmark add/deletion

[rmnvncnt]

Hi,

I am integrating Qlik Sense using enigma.js and following the related tutorial. This is my code currently :

  // Get bookmarks
  const bookmarkListModel = await app
    .createSessionObject({
      qInfo: { qId: "BookmarkList", qType: "BookmarkList" },
      qBookmarkListDef: { qType: "bookmark" }
    })
    .catch(errorHandler);
​
  const bookmarksUpdater = () =>
    bookmarkListModel
      .getLayout()
      .then(layout => (qlikApi.app.bookmarks = layout.qBookmarkList.qItems))
      .catch(errorHandler);
​
  // Reactive bookmarks
  bookmarkListModel.on("changed", bookmarksUpdater);
  await bookmarksUpdater();

The first call to the await bookmarksUpdater();  updates correctly my qlikApi.app.bookmarks variable, however deleting/adding bookmarks does not trigger the event.

I tried :

• Putting console.log everywhere. The bookmarksUpdater function is never called after the first time.
• Requesting some qData in the qInfo of the bookmarkListModel. No change.
• Using all the other events. None is triggered.

Do you have any clue on where to search next?

Hi @rmnvncnt , I tested your code and it works on my side. You are managing it in the correct way reacting to changes on your bookmarks list.

//----- React to bookmarks list changes -----
//Create bookmark list
const bookmarkListModel = await app
  .createSessionObject({
    qInfo: { qId: "BookmarkList", qType: "BookmarkList" },
    qBookmarkListDef: { qType: "bookmark" }
})

const bookmarksUpdater = () =>
  bookmarkListModel
    .getLayout()
    .then(layout => console.log("a"))
  
// Reactive bookmarks
bookmarkListModel.on("changed", bookmarksUpdater);
await bookmarksUpdater();

//Create a bookmark
const bookmarkDef = {
  "qInfo": {
      "qType": "bookmark"
  },
  "qMetaDef": {
      "title": "Bookmark (1)",
      "description": "",
      "isExtended": false
  },
  "creationDate": "2023-03-15T09:21:38.845Z",
  "sheetId": "bd37d32a-20c4-47e6-aeea-0838e98e1de2",
  "selectionFields": "Date"
}
const bookmarks = await app.createBookmark(bookmarkDef);
//Delete bookmark
await app.destroyBookmark(bookmarks.id);

Hi alex_colombo,

Thank you for testing. We managed to fix this issue.
For posterity, the issue was on the user session : we did not open a websocket session specifically for the app, we simply opened it for the engine and then re-used it for the app.
