打开时为空值

Question

我想使用select2 with Angular，有时打开select时会得到"empty"值。我不知道为什么会这样。

查看它的外观：

但是，有时它会完美运行：

真不知道为什么会这样。这是我的指令代码：

<div class='form-group' ng-show="items && items.length > 0">
<ui-select ng-model="selectedItem" on-select="onChange($item);" theme="bootstrap">
    <ui-select-match placeholder="{{placeholder}}">
        {{selectedItem[fillable]}}
    </ui-select-match>

    <ui-select-choices repeat="item in items | filter: $select.search">
        <span ng-bind="item[fillable]"></span>
    </ui-select-choices>
</ui-select>
</div>

这是我实例化它的方式：

<strainer-select
        items="campaigns"
        selectedItem="campaignSelected"
        handler="onCampaignFilterChanged"
        placeholder="Filtre por campanha"
        fillable="campaign"
    ></strainer-select>

有没有人见过这种情况？

非常感谢任何帮助。

谢谢大家

这可能是指令本身的错误。问题似乎在于其中的指令输入。所以解决方法是添加样式以强制 100% 宽度。

<!DOCTYPE html>
<html>

  <head>
    <script data-require="jquery@2.0.3" data-semver="2.0.3" src="https://code.jquery.com/jquery-2.0.3.js"></script>
    <link data-require="bootstrap-css@3.3.6" data-semver="3.3.6" rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.css" />
