AttachEditor2组件的上传机制疑问

xuechao0422

经过观察，我发现在使用AttachEditor2组件上传较大的数据时，后台在tomcat的目录下连续复制了两次数据的临时副本

首先复制2次

，然后在studio目录下又复制了一次数据的临时副本，

然后是在blobstore的doc___目录下复制数据的临时副本，这时上传过程才结束；
点击提交后，数据复制到了defaultDocNameSpace_____________目录下。
目前的疑问是
1：上传过程中，数据会被复制4次，时间较长，能否通过某种机制减少复制次数？
2：上传后点击提交，数据又要在后台复制一次，这时浏览器的页面是假死状态，能否把数据的复制改成剪切？
3：在下载数据时，点击下载按钮，弹出另存为窗口，这时如果取消下载，则后台会报一长串错误，这种情况是否是正常状态？

谢谢您的回复，那么关于我的第三个疑问呢？点击附件组件的下载按钮后，弹出下载对话框，这个时候取消下载，或者在下载过程中取消下载，那么后台会报很长串的错误，这个是正常现象吗？需要解决吗？

什么错误？把错误信息发一下，测试未报错

错误我分在两个帖子里回复的，一个帖子超出字数限制了
就是点击下载按钮后，弹出了另存为的对话框，这个时候取消，后台就会报错

xuechao0422

版本是X5.2.7，Window7 64位操作系统，浏览器用的chrome，附件200M左右。
弹出另存为对话框以后马上点击取消，后台就会报错，如果是下载过程中取消下载，报的错误也是相同的。我觉得是浏览器的下载工具都有预下载功能了。
下载过程中取消下载的话，报上述错误是正常的吗？谢谢

jishuang

chrome浏览器点下载就直接下载了，不会弹出另存为对话框

这个错误是向后台请求数据，在后台返回数据的时候前台已经取消了，导致返回的数据没有接收的地方就报错了，不会影响使用，

你好楼主，您反馈的这个现象通过验证是产品缺陷，我们已提交到产品组(内部编号：2014101400001)，感谢楼主的支持与配合。
