Hi,

A client has a strange problem, which i cannot reproduce.
He uses Vista, the bug is browser independant: IE 8.0, Firefox 3.5.1 or Chrome.
Applet loads fine, but on selecting files it doesn't show anthing.
Console log says:

Code: Select all

I tried deleting temporary javafiles, temp internetfiles, rebooting, nothing seems to work.

My client says the problem occured a few days ago, he plugged his pc into a different network (at work) and was transfering data from this LAN. Uploads were working fine!
Now he's back at home and cannot access the jfileupload again.
Maybe the uploader tries to find the last accessed location? Which isn't there anymore...

Any thoughts?

It looks like an internal JRE issue. Does drag&drop work ?
Also, could you ask which JRE version is used ?

[davinci]

drag n drop does work!
Using JRE version 1.6.0_13

It looks like a JRE bug in the built-in file chooser:

One solution is to make sure the following folder exists, could you try it?
"%HOMEDRIVE%%HOMEPATH%\Documents"

[davinci]

yup found it. it was pointing to a no longer existing location. Used regedit to change it back to default. Somehow the location of Documents was pointing to a network share...(which wasn't available anymore)
Thank you for your quick reply and pointing me to the right directions.
