Hello everybody,
I have setup a mapfile with 4 dimensions. As long as I have the dimension parameters in the request, it works fine. But if the dimension parameter are missing, the default parameters won't be used. What is wrong with my mapfile?

mapfile:
(...)
    METADATA
        "wms_title" "DWD Prognose Luft"
"wms_abstract" "Darstellung der Ausbreitungsrechnung in der Luft; Der Layer muss über die Variablen VID (Vorgangs-ID), MGR_ID (Messgrößen-ID), RIE (relatives Intervallende) abgefragt werden, ansonsten werden die Defaultwerte verwendet"
        "wms_enable_request" "*"
        INCLUDE "../../include/general/standard_extent_welt.map"

        "wms_dimensionlist" "MGR_ID,RIE,VID"
        "wms_MGR_ID_item" "MGR_ID"
        "wms_MGR_ID_extent" "373, 870, 384"
        "wms_MGR_ID_units" "none"
        "wms_MGR_ID_default" "373"

        "wms_RIE_item" "RIE"
        "wms_RIE_extent" "0, 6, 18, 30, 42, 54, 66, 78"
        "wms_RIE_units" "hour"
        "wms_RIE_default" "18"

        "wms_VID_item" "VID"
        "wms_VID_extent" "10000000/9999999999"
        "wms_VID_units" "none"
        "wms_VID_default" "984092599"

        "wms_timeitem" "TIME"
        "wms_timeextent" "2012-01-01 00:00/2012-12-31 00:00"
        "wms_timedefault" "2012-03-12 00:00"

        "default_MGR_ID" "373"
        "default_RIE" "18"
        "default_VID" "984092599"
    END


By the way I think, there is a documentation error:
In the documentation http://mapserver.org/ogc/wms_dimension.html under "Setting Up a WMS Layer with dimension support" the parameter "wms_[dimensionname]_units" is also mandatory, otherwise I didn't get it work.


Best regards,
Stefan
