I think also that Kosmo request to WMS Styles and Legends starts probably together with a WMS layer request. Since I didn't want to modify any original WMS OJ classes, OJ WMS legend plugin calls after a WMS is loaded. Infact there is a small delay on OJ whenever a user ask for a legend, comparing to the same process on Kosmo
