Sending an empty file (= 0 bytes) via "send file to partner" fails.
The AS2 main window displays: "Manual send: null"
Sending the same empty file via outbox directory succeeds without problems.
Why do you want to send 0 bytes to a partner?
To be honest: I don't want to send 0 bytes.
This was just an "accidental" finding.
I was suprised that sending the file via "send file to partner" fails,
whereas it succeeds to send it via outbox directory.
I thougth that you might be interested in my finding ... and a consistent behaviour of your software.
Ok, glad this is no show stopper. We will have a look at it.
