OpenLayers sets the parameter to uppercase MY.MAP.LAYER[MYLAYER]=DATA+shapefiles/shp2 Perhaps thats the problem

I am trying to dynamically change a layer's data source via url, specifically changing the DATA parameter in the MapServer map file. So for two spatially-indexed shapefiles (shp1, shp2): Manually changing the url works: http://host/cgi-bin/mapserv?map=my.map&LAYERS=myLayer&TRANSPARENT=true&SERVI CE=WMS&VERSION=1.1.1&REQUEST=GetMap&...&map.layer[myLayer]=DATA+shapefiles/s hp2 However when I use mergeNewParams: myLayer.mergeNewParams({"my.map.layer[myLayer]" : "DATA+shapefiles/shp2"}); or: myLayer.mergeNewParams({"myLayer" : "DATA+shapefiles/shp2"}); I get the error "msUpdateMapFromURL(): General error message. Layer to be modified not valid." From Firebug it looks like the layer name is converted to all caps which may be causing a mismatch, but copying and manually editing the OpenLayers request's layer name gives a different error: getString(): Symbol definition error. Parsing error near (+):(line 1) Any ideas?
