Hi,
i am trying to get the dynamic variable substitution work on Mapserver 
6.3dev but somehow it does'nt work as it worked before and as documented.
When i execute
http://10.10.4.18/cgi-bin/LI_USA-MT.cgi?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=48.046271,-115.929840,48.198407,-115.666914&CRS=EPSG:4326&WIDTH=1647&HEIGHT=953&LAYERS=data_view&STYLES=&FORMAT=image/png&DPI=96&TRANSPARENT=TRUE&STARTDATE=2011-01-01&ENDDATE=2013-09-01

or

http://10.10.4.18/cgi-bin/LI_USA-MT.cgi?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=48.046271,-115.929840,48.198407,-115.666914&CRS=EPSG:4326&WIDTH=1647&HEIGHT=953&LAYERS=data_view&STYLES=&FORMAT=image/png&DPI=96&TRANSPARENT=TRUE

I get an error in
  msDrawMap(): Image handling error. Failed to draw layer named 'data_view'.
msPostGISLayerWhichShapes(): Query error. Error executing query: ERROR:  
invalid input syntax for type date: "%STARTDATE%"
LINE 8: ...     (((acquisition_date >= date_trunc('day',date '%STARTDAT...
                                                              ^
So the substitution does not happen or the default is not applied.
Any hint on what i am doing wrong would be great.

See below the components from the mapfile:
