           Summary: MapDHTML: onerror remove spinner
           Product: Chameleon
           Version: 2.4
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Widget

Currently when the MapDHTML image loading fails (red cross), the spinner keeps
on running giving the user the indication that something is still gonna happen.

I propose to use the onerror event handler to also remove the spinner, i.e. the
following change in MapDHTML.js (add onerror=\"MapWHideActivityLayer();\"):

    content = "<img id=\"MapLayerDivImg\" galleryimg=\"no\"
name=\"MapLayerDivImg\" src=\""+gAPixel+"\" width=\""+gMapWiWidth+"\"
height=\""+gMapWiHeight+"\" border=\"0\" onload=\"MapWHideActivityLayer();\"
onerror=\"MapWHideActivityLayer();\"
onmouseover=\"MapWCaptureMouse(arguments[0]);\"
onmouseout=\"MapWReleaseMouse(arguments[0]);\">";
    CWCDHTML_CreateLayer("MapLayerDiv", gMapWhspc, gMapWvspc, gMapWiWidth,
gMapWiHeight,
                          true, content);
