check to make sure only one item was selected and to send the sessionID to a
custom page where the api is used to get the map and its selection set to
display the data. I think you need to use a full URL to call your custom
page because a relative URL will be relative to the viewer application.
This has worked well for me in the <st1:City w:st="on"><st1:place
w:st="on">AJAX</st1:place></st1:City> viewer. Jason stated that it will
not work in the DWF viewer but I haven’t tried it.<o:p></o:p></SPAN></FONT></P>
