DEAR PEOPLE FROM THE FUTURE: Here's what we've figured out so far???
I had setup a small application that load a Map control, but I did not define a base map, therefore when the application runs, it only shows a blank space.
then I proceed to load a shapefile in a local dynamic layer and add it to the map.
I forgot to mention that I also added a legend control bond to the map...so if I add the shapefile, the legend shows me the name of the layer and the symbol.
Why does the features in the shapefile are not shown?
