[mapguide-users] Buffer Problem

[padmini godavarthi]

Hi, 
iam using mapguide opensource 2.0 (with .net 2.0 +IIS 5.1) 

i have 2 problems 

1) while creating buffer using built in command in maestro i got the following error as 



    

my map  is  in   WGS 84 (EPSG:4326)  coordinate system 
can u tell me the solution???????????????? 

2) secondly,i  have added one invoke script command for buffering (i want to display the buffer in new pop up window) but i got an error in bufferui.tmpl 


function FillLayerList() 
{ 

alert('FillLayerList'); 
    var list = document.getElementById("layers"); 
alert(list); 
    var listNames = document.getElementById("layerNames"); 
alert(listNames); 
    list.options.length = 0; 
    var layers = GetParent().GetMapFrame().GetSelectedLayers(); 

    if(layers.length > 0) 
    { 
        for(var i = 0; i < layers.length; i++) 
        { 
            var layer = layers[i]; 
            list.options[i] = new Option(layer.legend != ""? layer.legend: layer.name); 
            if(i == 0) 
                list.options[0].selected = true; 
            listNames.options[i] = new Option(layer.name); 
alert(layer.name); 
        } 
    } 
    else 
      
        list.options[0] = new Option("__#BUFFERNOLAYER#__"); 
    document.getElementById("Done").disabled = layers.length == 0; 
} 

i got the error at 

   var layers = GetParent().GetMapFrame().GetSelectedLayers(); 

Is there any modification is needed?????????????

Padmini
