Can you help me with the javascript error bellow?
"NetworkError: 404 Not Found - /pmapper/projCode/null.js"

My map projection is :
  PROJECTION
    "init=epsg:3857"
  END # PROJECTION
and my config xml
            <unitAndProj>
                <projections>
                    <prj name="WEB-mercator">
                        <definition>init=epsg:3857</definition>
