[mapserver-users] Problem setting name attribute of classObj with Python Mapscript

[Sean Gillies]

Have any Python (or other) Mapscript users found trouble with
setting the "name" attribute of a classObj?  I've been through
the list archives but haven't found anything of help.

In short, I'm unable to set the name attribute of a classObj
by statements like

   myclass.name = "FOO"

Am using Python Mapscript built from the 3.5 Win32 distribution.

Here is the relevant code of my script. Am looping over several
layers in a list and ftab['name'] is bound to a different value
each time.

   ...
   class_OK = classObj(layer)
   class_OK.setExpression("/1/")
   class_OK.name = ftab['name'] + "_OK"
   class_OK.outlinecolor = purple # 255,0,255

   class_DEF = classObj(layer)
   class_DEF.name = ftab['name'] + "_DEF"
   class_DEF.color = red
   class_DEF.outlinecolor = purple
   class_DEF.label.color = black
   class_DEF.label.type = MS_BITMAP
   class_DEF.label.size = MS_TINY
   class_DEF.label.position = MS_CC
   class_DEF.label.force = MS_TRUE
   ...
   map.save(...)

The map is drawn and looks fine, but no legend.  Examining the
map file that was written, I see that everything is in its
place except that there is no NAME for either of the two classes
I've defined for every layer.  Here is an excerpt from the map
file:

   CLASS
     EXPRESSION /1/
     MAXSIZE 100
     MINSIZE 1
     OUTLINECOLOR 255 0 255
     SIZE 1
     SYMBOL 0
   END
   CLASS
     COLOR 255 0 0
     LABEL
       SIZE TINY
       TYPE BITMAP
       BUFFER 0
       COLOR 0 0 0
       FORCE TRUE
       MINDISTANCE -1
       MINFEATURESIZE -1
       OFFSET 0 0
       PARTIALS TRUE
       POSITION CC
     END
     MAXSIZE 100
     MINSIZE 1
     OUTLINECOLOR 255 0 255
     SIZE 1
     SYMBOL 0
   END

Am stumped and grateful for any suggestions.

thanks,
Sean
