部件号：MSP430FR2633
主题中讨论的其他部件：Captivate电话， Captivate金属

在 Captivate设计中心(1.50 ．00.00 ，Windows)中切换项目时，我无法再打开任何项目。

在CaptivateDesignCenter.log中，我看到NullPointerException：

线程"AWT-EventQueue-0"中出现异常

删除项目文件夹CaptivateDesignCenter_1_50_00_00并重新启动Captivate设计中心后，我可以再次打开项目。 但在项目之间切换仍然不起作用。

    Wouter您好，

    首先让我们确认一些基本信息。 您运行的是什么操作系统？ 您使用的是哪个版本的Java？
    您是否还可以提供错误发生前屏幕的屏幕截图？ 这可以帮助我们找到正确的方向来了解正在发生的事情。
    一种可能是文件路径太长。 是否可以向上移动工作区路径并查看错误是否仍然存在？

    您好，Jace：

    感谢您的回复。

    我现在使用的是Windows 10，Java 8 update 151 (64位)。

    下面是这种情况的屏幕截图。 每次单击'elect'(选择)时，NPE都会出现在日志中，并且此弹出窗口不会关闭。

    下面是NPE之前包含一些附加信息的日志：

    您好，

    我们认为我们知道您现在正在做什么。 您似乎正在加载工作空间和项目(根据默认启动)，然后尝试在新项目所在的相同位置打开新工作空间。 这种开端似乎打破了GUI。 如果您只想启动一个新项目，只需使用文件->项目打开或文件->项目->新建，而不尝试启动新工作区。 如果您确实需要一个完全不同的工作空间，而不是缺省值，则需要创建一个工作空间，该工作空间不在示例工作空间或与项目不在同一文件夹下。 在新工作区中，创建一个新的子文件夹，作为新项目。

    我们将在跟踪器中添加此问题，以便在将来进行改进。

    再次感谢您的快速响应。

    嗯，我不是在尝试创建新项目，而是打开不同的(现有)示例项目。 现在我得到了：我必须选择一个比我要打开的项目高一个文件夹级别的工作区。 选择正确的工作空间文件夹(本例中为CapTIvateDesignCenterWorkspace)后，我可以打开不同的示例项目。
