[Chameleon] Problem with Label Layer Widget

[listserver server]

This is the layer definition in mapfile:
LAYER
  NAME "scuole"
  METADATA
    wms_title "scuole"
    wfs_title "scuole"
     "DESCRIPTION"   "comune"
    "RESULT_FIELDS" "comune"
    "LAYER" "scuole"
     gml_include_items "all"
    END
  STATUS ON
  DUMP TRUE
  TYPE POLYGON
  CONNECTIONTYPE POSTGIS
CONNECTION "user=postgres password=postgres dbname=NEW host=localhost
port=5432"
DATA "the_geom FROM (select comune, I02_97 as Elementari_Classi, I03_97 as
Medie_Classi, I04_98 as Superiori_classi, the_geom, gid from scuole) AS
scuole USING UNIQUE gid USING SRID=-1"
  classitem "comune"
PROJECTION "init=epsg:26591"
  END
LABELITEM comune
 CLASS
    NAME "comune"
   TEMPLATE "ttt_query.html"
   OUTLINECOLOR 0 0 0
    LABEL
      TYPE truetype
      FONT sans
      SIZE 7
      COLOR 0 0 200
      POSITION auto
    END
END

This is the widget definition of Label çayer Widget:

<cwc2 type="LayerLabels" styleresource="TextButtons" label="Label Layers"
popupwidth="500" popupheight="280" image="icons/icon_labels.png"
Toolbar="false"
Status="false" Menubar="false" ImageTip="Add Labels to a layer in the
current map." >
           <image state="normal"/>
           <image state="selected"/>
           <image state="hover"/>
        </cwc2>

Problem is always the same as i reported in list here
http://lists.maptools.org/pipermail/chameleon/2006-May/004103.html
I can choice Layers but i cannot see Attributes of Layers!

I'm using Chameleon MS4W and Postgis
