Original question:
原提问：e2echina.ti.com/.../ccstudio-ccs-view--expression
新建立的CCS工作空间，Expression是空白的，于是向往这里面增加一些变量用于观察，特别是在程序调试运行的时候观看
然而，经过一段时间后，就会出现在程序运行界面选择View->Expression，无法弹出观察窗口，只有把视图从CCS Debug切换至CCS Edit，该观察窗口才可以弹出来
不知道是否是CCS的bug？已经多次出现了
解决办法目前是把workspace里的内容全都删除掉（这样Expression里之前添加的观察变量也会被清空），然后再重新添加，就又正常了
推测是不是workspace里的缓存影响到了View->Expression的查看？
再次复现了该问题，对应的关闭 CCS 并提供 <WORKSPACE FOLDER>/.metadata/.log 文件（附加到此线程）
该log最后的信息如下：
