Renderer for the "automatic" script-only page that is produced to send a map of values from a popup window
back to the opener, and to close the popup window.
Render the JavaScript for this framework response to a popup window.
The JavaScript passes a map of field values from the popup back to
a JavaScript routine on the originating page updating its form fields.
(See
org.apache.beehive.netui.tags.html.ConfigurePopup )
The javascript also closes the popup window.
