Hi, all.
My env is like the following.
NW2004s SPS11.
i tried the file upload/download sample.
Uploading and Downloading Files in SAP NetWeaver 7.0
/people/bertram.ganz/blog/2007/05/25/new-web-dynpro-java-tutorials--uploading-and-downloading-files-in-sap-netweaver-70
Of course, it works well in normal situation but in the following case,
it has some problem.
- How to produce : enter directly(for example, enter
"test.xls" without directory path) directly into the input field
of FileUpload UI
- Phenomena : Java Script error occurs and the program runs infinitely.
Is this a known problem?
And is there any workaround for this? For example, set the input field to
read-only or implement the input field of FileUpload UI validation check?
Best Regards.
