Comment (by liuar):

 mapName is a local variable defined in function FillLayerList(). If
 there's no object selected, there will be a error like mapName is
 undefined in


 {{{
 function OnCancel()
 {
     var map = GetParent().Fusion.getMapByName(mapName);
     map.clearSelection();
     //mf.GotoHomePage();
 }
 }}}


 so, the solution is make the mapName a global variable and check the value
 of mapName before getting the map.[[BR]]

 {{{
 function OnCancel()
 {
     if(mapName == "undefined")
         return;

     var map = GetParent().Fusion.getMapByName(mapName);
     map.clearSelection();
     //mf.GotoHomePage();
 }
 }}}
