Question about map.Create and map.Open() on the mapframe

[Trevor Wekel]

Hi Scott,
 
mapframe.jsp should only be called when a complete refresh of the page
is requested by the browser.  The page refresh was intended to get a new
copy of the map so the Create() call is appropriate.  If a user wants to
refresh just the map pane they can right click in the pane and hit
refresh.  A Refresh Icon can also be added to the WebLayout toolbar.
 
User sessions were not intended to go beyond the lifetime of the browser
session.  Certainly it is possible to do as you have found out with
modifying mapframe.jsp.  Just out of curiosity, how did you get around
the CreateSession() in mainframe.jsp?
 
Thanks,
Trevor

Subject: Question about map.Create and map.Open() on the mapframe


All,
I have a questions about loading a map from a saved MgSession.  I also
think there is a possible bug in the mapframe.jsp page that prevents the
page from loading a map saved in an open MgSession

In the mapframe.jsp the page always calls map.Create() forcing a new Map
to be drawn, even if the calling Session already has a Map object
associated to it with the same name.  Shouldn't the mapframe.jsp page do
a check to see if the map has been created to the calling MgSession and
call a map.Open() rather then a map.Create() so that the map will have
the proper layers saved in the users session?
 
I want to have the users map and dynamic layers persist throughout their
MgSession, but with the current code when the users accesses the main
page it always creates a new map (map.Create()), rather then doing a
check and a map.Open().   When I changed this code, the application
performs as expected and loads in the proper map for the users
MgSession.  
 
Any help is much appreciated.
 
Thanks,
-scott
