 273      *    As a workaround I tried jquery.form.js version 2.49. The file
 274      *    upload worked but afterwards the browser presented a tbl_replace.php
 275      *    file and a choice to open or save.
 276      *
 277      * 2. This code can be called if we are editing or inserting. If editing,
 278      *    the "and then" action can be "go back to this page" or "edit next
 279      *    row", in which cases it makes sense to use AJAX. But the "go back
 280      *    to previous page" and "insert another new row" actions, using AJAX
 281      *    has no obvious advantage. If inserting, the "go back to previous"
 282      *    action needs a page refresh anyway.
