Does MapServer support WMS time series using polygon shapefiles?

[Peter Shrock]

Hello,all:

I am having difficulties to make WMS time series work. 

I am using mapserver 4.10.0. I tested point data with time dimension, it
worked. I tested tiled polygons, it worked. 

But I cannot get polygon shapefile work for time series WMS 

I used identitical polygon shapefiles, one shapefile for one year. tile index
shapefile (index1.shp) was created using tile4ms.exe, and I verified the
contents of the file.

I tried two methods in order to make the WMS time series work. Both failed. 

Could you please help me?

# Test method 1: everything in one layer object 
LAYER 
  NAME "timemap" 
  TYPE RASTER 
  STATUS ON 
  METADATA 
        "wms_title" "timemap" 
        "wms_timeformat" "YYYYMMDD" 
        "wms_timeextent" "20021130/20061130" 
        "wms_timeitem" "DATETIME" 
        "wms_timedefault" "20021130" 
        "wms_srs" "EPSG:4326" 
   END 
   TILEINDEX "index1.shp" 
   TILEITEM  "Location" 

    CLASSITEM "color_code" 
    CLASS 
    NAME  "TYPE 1" 
      EXPRESSION ([color_code]==1) 
      COLOR      220 120 130

        OUTLINECOLOR 100 100 100 
    END 
END # one layer object method 


# Test method 2: seperate tileindex layer and data layer 
LAYER 
    NAME "mylayer" 
    STATUS ON 
    TYPE RASTER 
    TILEINDEX "index1" 
    TILEITEM "Location"

    "init=epsg:4326" 
  END 

  METADATA

END 

LAYER 
  NAME "tidx" 
  TYPE TILEINDEX 
  STATUS ON 
  DATA index1 
  FILTERITEM 'DATETIME' 
  FILTER '%DATETIME%' 
END # tile layer 

The error message is: 
msDrawMap(): Image handling error. Failed to draw layer named 'timemap'.
msDrawRaster(): Image handling error. Unrecognized or unsupported image format
drawEPP(): Image handling error. EPPL7 support is not available. 

The error message does not seem helpful.

Thanks

Peter
