Labels are not displayed in 4.4.1

[Björn Platzen]

Hello List,

I just upgraded from Version 3.6.5 to 4.4.1 and now some of my labels don't
seem to appear...

Here's a snippet from the mapfile:

These Labels don't appear:
    LAYER
      NAME "beschriftung1"
      TYPE ANNOTATION
      DATA "labels"
      STATUS ON
      CLASSITEM "Level"
      LABELITEM "Text"
      LABELANGLEITEM "Angle"
      SYMBOLSCALE 6500
      LABELCACHE on
      CLASS
        EXPRESSION "1"
        MAXSCALE 25000
        LABEL
          ANTIALIAS true
          TYPE TRUETYPE
          FONT swiss
          MINSIZE 6
          SIZE 8
          MAXSIZE 10
          COLOR 0 0 0
          FORCE true
          POSITION uc
        END
      END
      CLASS
        EXPRESSION "43"
        LABEL
          TYPE TRUETYPE
          FONT swiss
          ANTIALIAS true
          MINSIZE 8
          SIZE 12
          MAXSIZE 16
          COLOR 0 0 0
          FORCE true
          POSITION uc
        END
      END
    END

These Labels _do_ appear:
    LAYER
      NAME quartiere
      TYPE POLYGON
      STATUS on
      MAXSCALE 200000
      DATA quartiere
      CLASSITEM "ID"
      LABELITEM "Name"
      LABELMINSCALE 8000
      LABELCACHE off
      CLASS
        EXPRESSION '1'
        STYLE
          SYMBOL 'circle'
          SIZE 6
          OUTLINECOLOR 131 157 197
        END
        LABEL
          #FORCE TRUE
          ANTIALIAS true
          POSITION auto
          SIZE 10
          TYPE TRUETYPE
          FONT swiss
          COLOR 0 51 255
          #OUTLINECOLOR 0 0 0
        END  # Label
      END  # CLASS
      template "rahmen_q.html"
    END #LAYER

With version 3.6.5, all the labels appeared. So I think, there must have
been some changes in the mapfile-syntax for labels, but I wasn't able to
find out what...

So, if anyone has an idea, please give me a hint.

Thanks and bye,

Bjoern
