           Summary: map crash when using keymap widget and no reference
                    object in MAP file
           Product: Chameleon
           Version: 2.0
          Platform: PC
        OS/Version: Windows 2000
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core
        AssignedTo: chameleon-dev at lists.maptools.org
        ReportedBy: bartvde at xs4all.nl


Today I struggled with the following.

I tried to use a copy my MAP file in the Chameleon samples by renaming it to
world_wms.map.

But then I got:
Error rendering map image. A fatal error has occurred .... please restart the
application.

When digging into this, I found this was caused by my MAP file missing a
REFERENCE object, and my template having a KeyMapDHTML widget. But it took a lot
of digging :).

The cause is apparently in the generated session MAP file which gets a default
extent of -1 -1 -1 which causes this:

  REFERENCE
    COLOR 255 0 0
    EXTENT -1 -1 -1 -1
    IMAGE "C:\ms4w\apps\chameleon\samples\htdocs/images/world_key.png"
    OUTLINECOLOR 0 0 0
    SIZE 0 0
    STATUS OFF
      MARKER 0
      MARKERSIZE 0
      MINBOXSIZE 3
      MAXBOXSIZE 0
  END

Can anything be done about this?
