Angular js错误：找不到指令yyyy所需的[$ compile：ctreq]控制器xxxx

Question

I already multiple topics on stackoverflow about this error but I always don't understand the problem in my context.

I have this template:

<div class="progress">
<div class="progress-bar"
     data-toggle="tooltip"
     title="Parts offertes : {{ '{{ gift.gived_parts}}' }} / {{ '{{ gift.number_of_parts }}' }}"
     data-bar="gived"
     >
    <span ng-class="{true:'op7', false:''}[gift.percent_done > 0 && gift.percent_done < 20]">
        {{ '{{ gift.gived_parts}}' }}
    </span>
</div>
<div class="progress-bar progress-bar-danger progress-bar-striped progress-bar-animate active op7"
     data-toggle="tooltip" 
     title="Parts réservées&nbsp;:&nbsp;{{ '{{ gift.total_reserved}}' }}&nbsp;/&nbsp;{{ '{{ gift.number_of_parts }}' }}"
     data-bar="reserved">
</div>

For this directive:

app.directive('progressBarD', function() {
return {
    restrict: 'E',
    templateUrl: rootUrl + '/directive/progressBar',
    scope: {
        gift: '=gift'
    },
    link: function ($scope, $elem, attrs) {
        var bars = $elem.find(".progress-bar");
        bars.each(function() {
            var bar = $(this);
            var percent = (bar.context.dataset.bar === "gived")
                ? $scope.gift.percent_done
                : $scope.gift.percent_reserved;

            if (($().appear) && isMobileDevice === false && (bars.hasClass("no-anim") === false) ) {
                bar.appear(function () {
                    bar.addClass("progress-bar-animate").css("width", percent + "%");
                }, {accY: -150} );
            } else {
                bar.css("width", percent + "%");
            }
        });
    }
};
});

And here is the call of the directive:

<progress-bar-d gift="gift"></progress-bar-d>

During the execution, I obtain this error:

Error: [$compile:ctreq] Controller 'progress', required by directive 'bar', can't be found!

On the screen, the link function look to work, but at the end, the inside the first desapear when gift.percent_done is different of 0.

Could you explain me why I have this angular error ? Do the deletion of the span is the same problem ?

Answer 1

Finally I found the problem.

In the anguluar directive I change bar.context.dataset.bar and it work. I don't know why that was not well interpreted but now it work.
