SID-01415: Can't upload attachments with IE

Status:	Answered	TWiki version:	5.1.1	Perl version:	5.8.8
Category:	CategoryAttachments	Server OS:	AIX 5.3	Last update:	13 years ago

We just installed TWiki 5.1.1 at our site and uploading attachments isn't working from IE. It does work from Firefox (Windows or Linux). There's no error reported to the user, the attachment just doesn't show up in the topic. This error shows up in the server logs:

[Mon Feb 27 11:31:25 2012] [error] [client <deleted>] [Mon Feb 27 11:31:25 2012] upload: Use of uninitialized value in concatenation (.) or string at /local/web/twiki5/lib/TWiki/UI/Upload.pm line 423., referer: http://<deleted>/twiki/bin/attach/Develop/DevWikiTest

This is the code it refers to:

# generate a message useful for those calling this script from the command line 
my $message = 
   ($doPropsOnly) ? 'properties changed' : "$fileNames[0] uploaded";

I'm assuming @fileNames is empty for some reason. Anyone else encountered this and have a solution/workaround?

Discussion and Answer

FYI, I got rid of the error by changing the code to this:

 # generate a message useful for those calling this script from the command line
    my $message_file_name = $fileNames[0] ? $fileNames[0] : '???';
    my $message =
      ($doPropsOnly) ? 'properties changed' : "$message_file_name uploaded";

It doesn't solve the original problem, though. You still can't upload attachments with IE.

I am also facing the same problem with IE
