手动将列添加到rallycardboard组件

我正在创建一个

rallycardboard

，其中每一列代表一个发行版，这些卡片是要安排到这些发行版中的功能。组件的默认机制将所有可用版本呈现为板上的列。对于我们的特定应用程序，这是不合理的，因为我们的工作区中有数千个版本

我能够覆盖

addColumn

方法，仅在组中至少分配了一个功能的版本中包含一个列。下一步是让用户可以手动添加当前没有任何分配工作的发布列。为此，我存储了第一步中排除的所有列，并用这些值创建了一个组合框。我希望这样，当用户从组合框中选择发布时，该发布列将添加到板中

我能够重新配置我的

addColumn

方法，以允许手动覆盖（与尝试与现有功能的版本相匹配）。我通过调用

board.getColumns（）

验证了该列已添加到boards列，并且现有列和添加列的配置看起来都相同。但是，调用board.renderColumns（）时，我收到一条错误消息，这似乎是试图写入一个尚不存在的容器（该列尚未创建）的结果

也许我走错了方向。是否有其他方法可以更轻松地决定在

rallycardboard

组件上包括哪些列以及排除哪些列

---

以下是一个示例，其中board列基于具有预定功能的发行版。要为当前没有计划功能的发布添加列，请从mulitpicker中选择releases
