This a bug -- I just submitted a pull request to fix it:
https://github.com/web2py/web2py/pull/1746.
For now, you can make that same change in your own web2py.js.
Note, this is only an issue if (a) you have a form with multiple submit
buttons and (b) clicking one of the submit buttons returns a file
*attachment*.
Also, technically, the code you have shown below does not actually result
in a problem because the "Content-Disposition" of the file is not set to
"attachment", so the browser simply displays the (empty) PDF in place of
the original page before the buttons are re-enabled. The problem only
appears if you add:
response.headers["Content-Disposition"] = 'attachment'
