When you preview a PDF from inside designer, it uses a temp filename for the doc and therefore when you test xml submit etc you will get the 'e.g. _e8hfydsh55hsksdf.xml' as a filename. However if the form is saved locally (e.g. MyForm.pdf) and you use Reader / Acrobat to open the PDF, then the email's subject message as well as the xml file will be MyForm.xml. Does that help you?
G'day Dallas *again* , yeah-- basically; but I was hoping to make filenames unique? If I can't, it's not a huge detriment. Cheers Dyr
To the best of my knowledge the XML attachment's filename will always match name of the PDF. My only other suggestion would be for you to change the name of the PDF or XML before you email it.
