[Tilecache] STYLES appears Twice in WMS Request

[Andrew Hughes]

Hi Y`all....

My WMS requires a STYLES parameter... I can submit this via the url 
parameter (as below), and as noted in the tutorial... 
http://docs.codehaus.org/display/GEOSDOC/TileCache+Tutorial
However, the styles parameter is added in once again by TileCache when 
it constructs the WMS request.

The WMS request looks *like*

http://localhost/wms?bgcolor=%2399B3CC&STYLES=,,,,,,,,,Railway_Case,,,,,Roads_Case,Freeways_Case,,MallRoad,MediumRoads,MajorRoads,,&BBOX=...&STYLES=&LAYERS=.....

Note that STYLES appears twice :'( which causes some confusion for the 
WMS....

I've looked at the code but I can't figure how how this is added to the 
URL....

tilecache.cfg layer looks like:

[MyLayer]
type=WMSLayer
url=http://localhost/wms?bgcolor=%2399B3CC&STYLES=,,,,,,,,,Railway_Case,,,,,Roads_Case,Freeways_Case,,MallRoad,MediumRoads,MajorRoads,,
srs=EPSG:4326
layers=a,b,c,d,e,f,g,h,i,dummy
extension=jpg
metaTile=yes
metaBuffer=0


Any help would be great!
