Paul,
we had a similar problem using GeoWebCache. You need to define a url
where the legend can be found at. in the example below we put a
GetLegendGraphic request to the WMS layer in as the URL.
Here's the workaround I posted a while back:
This is relevant when using the GeoWebCache that is built-in to
GeoServer 2.0.1, and the GeoExt legendPanel. It might be relevant in
other situations as well.
Use the mapPanel.layers.layer Set legendURL method to manually define
the wms getLegendGraphic parameter
I found the example at
http://dev.geoext.org/trunk/geoext/examples/legendpanel.js
here's a snippet of my code:
//
var LayerRec = mapPanel.layers.getAt(3);
LayerRec.set("legendURL","http://something.com/geoserver/wms?FORMAT=image/gif&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetLegendGraphic&EXCEPTIONS=application/vnd.ogc.se_xml&LAYER=medford:schools";);
//
I'm manually setting the index in "getAt(3)" to the 4th layer added to
my map. I haven't learned the proper syntax yet to get that index using
layer name, but I'm sure it can be done; just need to study more.

Thanks...
Is there any config to set tilecache off to legend?

TileCache doesn't do legend graphics, so if you're trying to talk
to TileCache to request an image other than a tile, you're going to
be out of luck.
