           Summary: [Chameleon-Core]Invalid map size in CWCInitializeMap
                    when the current state and map are not set
           Product: Chameleon
           Version: 2.6
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core
        AssignedTo: chameleon-dev at lists.maptools.org
        ReportedBy: nsavard at mapgears.com


When a Chameleon application is used as a service instance, a new map object is
created in CWCInitializeMap with an invalid size (1).  This happens because
msMapSetExtent (mapobject.c) calls msAdjustExtent (maputil.c) which does a
width-1 and height-1 calculation (see below).

  ox = MS_MAX(((width-1) - (rect->maxx - rect->minx)/cellsize)/2,0); /* these
were width-1 and height-1 */
  oy = MS_MAX(((height-1) - (rect->maxy - rect->miny)/cellsize)/2,0);
