[mapguide-users] Listing Active selected feature C#

[Knight, Gregory]

I have a C# example where I am doing exactly this. I can send you the page via separate means if you are interested.

I am attempting to get the list of selected parcels by using "Invoke URL"
command, passing "$Current Selection" to my "listdwfparcels.aspx" page,
through the key & value pair.

I don't know what I'm doing wrong, getting unclassified exception
"MgSelection.FromXml" . . .

Checking the value of my mgkey content "$Current Selection" returns:

%3C%3Fxml%20version%3D%221.0%22%20encoding%3D%22UTF-8%22%3F%3E%0A%3CFeatureSet%3E%0A%3CLayer%20id%3D%22d6a8101a-ffff-ffff-8003-000000000038%22%3E%0A%3CClass%20id%3D%22Default%3AHelkot%22%3E%0A%3CID%3ETAAAAA%3D%3D%3C%2FID%3E%0A%3CID%3EVwAAAA%3D%3D%3C%2FID%3E%0A%3CID%3EVgAAAA%3D%3D%3C%2FID%3E%0A%3C%2FClass%3E%0A%3C%2FLayer%3E%0A%3C%2FFeatureSet%3E%0A

Here is portion of the code that I'm using -

String mgSessionId = GetParameters()["SESSION"];
String mgSelection = GetParameters()["mgkey"];
MgResourceIdentifier layerFeatureResource;
MgReadOnlyLayerCollection layers;
MgSelection selection;
MgLayer layer;
string layerClassName;
string selectionString;
string layerFeatureId;
 
 
 try
        {
  InitializeWebTier();

  MgUserInformation userInfo = new MgUserInformation(mgSessionId);
  MgSiteConnection siteConnection = new MgSiteConnection();
  siteConnection.Open(userInfo);

  MgResourceService resourceService =
siteConnection.CreateService(MgServiceType.ResourceService) as
MgResourceService;
  MgFeatureService featureService =
siteConnection.CreateService(MgServiceType.FeatureService) as
MgFeatureService;
  MgFeatureQueryOptions queryOptions = new MgFeatureQueryOptions();
  
  MgMap map = new MgMap();
  map.Open(resourceService, "HaifaMap");
  
if (GetParameters()["SESSION"] != "")
{
    selection = new MgSelection(map, mgSelection);

<<<<< MY ERROR >>>>>
An unclassified exception occurred.An unclassified exception occurred.
Exception occurred in method MgSelection.FromXml at line 158 in file
c:\build_tux_area\mgdev_opensource\common\service\maplayer\Selection.cpp
