Hi Worth, If you want the scaledenom to be compute after the creation of the map object you can use the (mapObj) function prepareQuery(). With this method you are able to leave the state of the map object intact for using it later for draw() setExtent() etc.. If setExtent, draw, drawQuery is used, then of course the scaledenom is computed and rewritten.
