I wish to call dealCardSelectableAI(), have it chooseCards(), then use the output to set an observable system.star.cardList(), then call setCardName(). Once all this is done I want saveGame() to execute.

However, setCardName() is not completing before saveGame() is called, so apparently I can't push it into my deferredQueue via a .then().

I'm using jQuery due to working within an ES5 environment.

var setCardName = function (system, card) {
  var deferred = $.Deferred();
  require(["cards/" + card[0].id], function (data) {
    var cardName = loc(data.summarize());
    system.star.ai().cardName = cardName;
    deferred.resolve();
  });
  return deferred.promise();
};

var dealCardSelectableAI = function (win, turnState) {
  var deferred = $.Deferred();

  // Avoid running twice after winning a fight
  if (!win || turnState === "end") {
    var deferredQueue = [];

    _.forEach(model.galaxy.systems(), function (system, starIndex) {
      if (
        model.canSelect(starIndex) &&
        system.star.ai() &&
        system.star.ai().treasurePlanet !== true
      ) {
        deferredQueue.push(
          chooseCards({
            inventory: inventory,
            count: 1,
            star: system.star,
            galaxy: game.galaxy(),
            addSlot: false,
          }).then(function (card) {
            system.star.cardList(card);
            deferredQueue.push(setCardName(system, card));
          })
        );
      }
    });

    $.when(deferredQueue).then(function () {
      deferred.resolve();
    });
  } else {
    deferred.resolve();
  }

  return deferred.promise();
};

dealCardSelectableAI(false).then(function () {
  saveGame(game, true);
});

I tried resolving this by changing the function calls so setCardName() was chained following dealCardSelectableAI(). However, it relies on system.star.cardList() having been written, which in some circumstances had not yet been done.

Given the dependency system.star.cardList() has on chooseCards(), I cannot figure out how to make sure it has been written to before calling setCardName() in a way which blocks saveGame() until everything is done.
