Dual Web Action - Save/Post in formula & force file download save via bkgrd agent.

The example below was used in Global Data Collect. It performs four steps: (1) Sets the flag fields and download date (2) Saves/posts the document which refreshes in the browser to show the new status (3) OnSubmit checks which button was pressed and sends a URL to the browser (after the refresh) to download the file. (4) The background agent extracts the UNID from the URL string, gets a handle on the parent document, sends a print statement to the browser to force the open/save dialog box (otherwise PDFs would open in browser automatically), and finally sends the file URL to the browser to kick off the download.
