What you mean 'not found'?
You can either apply that to me thinking that attaching a file to my InfoPath form would be easy or MS for allowing such a nasty insidious bug to crawl out into production.
Here's the issue. I have an InfoPath form running under MOSS Enterprise forms services. Upon this form I have a couple of file attachment controls. One would thunk that given that file attachment controls seem to have been a part of HTML since the mid 1990's that this should be a totally elementary operation.
Heh, think again.
I found this out the hard way when, after browsing to my file and pressing the Upload button I was met with a rather curt 'The Selected File was not found' error message.
here is sol'n Add the attribute enctype="multipart/form-data" to this tag and save.
