I have a custom Sitecore ribbon button to import data from an uploaded file. The import dialogue is working, but when it goes into the postback, args.HasResult is returning as false

public abstract class ImportCommand : Command

{

    protected const string XamlControlPage = "/sitecore/shell/~/xaml/Sitecore.Shell.Applications.Dialogs.Bayer.UploadFile.aspx";

    private const string MasterDb = "master";



    protected ISitecoreService SitecoreService;

    protected IItemService ItemService;



    /// <summary>

    /// Executes the command in the specified context.

    /// </summary>

    /// <param name="context">The context.</param>

    public override void Execute(CommandContext context)

    {

        Initialize();



        Assert.ArgumentNotNull(context, "context");

        if (context.Items.Length != 1)

            return;



        Item obj = context.Items[0];

        var parameters = new NameValueCollection();

        parameters["uri"] = obj.Uri.ToString();

        parameters["id"] = obj.ID.ToString();

        Context.ClientPage.Start(this, "RunPipeline", parameters);

    }



    protected void Initialize()

    {

        var db = Sitecore.Configuration.Factory.GetDatabase("master");

        SitecoreService = new SitecoreService(db);

        ItemService = new ItemService(SitecoreService);

    }



    protected void RunPipeline(ClientPipelineArgs args)

    {

        if (!args.IsPostBack)

        {

            var url = new UrlString(UIUtil.GetUri(XamlControlPage));

            SheerResponse.ShowModalDialog(url.ToString(), "580", "300", string.Empty, true);

            args.WaitForPostBack(true);

            return;

        }



        if (!args.HasResult)

            return;



        try

        {

            var itemId = new Guid(args.Parameters["id"]);

            using (new BulkUpdateContext())

            {

                DoStuff(itemId, args.Result);

            }

            SheerResponse.Alert("Import Successful. Press OK to continue.");

        }

        catch (Exception ex)

        {

            SheerResponse.ShowError(ex);

        }

        finally

        {

            // Try deleting the file

            try

            {

                File.Delete(args.Result);

            }

            catch (Exception e)

            {

                Sitecore.Diagnostics.Log.Warn(string.Format("Unable to delete file: {0}", args.Result), e, this);

            }

        }

    }

}

I have a file UploadFile.cs that is handling the dialog:

public class UploadFile : DialogPage

{

    protected FileUpload fileUpload;

    protected Literal ltrlResult;



    protected bool IsFirstLoad

    {

        get { return ViewState["Upload.IsFirst"] as string != "false"; }

        set { ViewState["Upload.IsFirst"] = !value ? "false" : null; }

    }



    protected string FilePath

    {

        get { return ViewState["Upload.FilePath"] as string; }

        set { ViewState["Upload.FilePath"] = value; }

    }



    protected override void OnLoad(EventArgs e)

    {

        if (IsFirstLoad)

        {

            ltrlResult.Text = "First upload a file, then click OK.";

            IsFirstLoad = false;

        }

        else

        {

            ltrlResult.Text = string.Empty;



            var fileOK = false;

            var path = HttpContext.Current.Server.MapPath("~/Upload/");

            if (fileUpload.HasFile)

            {

                var fileExtension = Path.GetExtension(fileUpload.FileName).ToLower();

                string allowedExtensions = {".csv"};

                for (int i = 0; i < allowedExtensions.Length; i++)

                {

                    if (fileExtension == allowedExtensions[i])

                    {

                        fileOK = true;

                    }

                }

            }



            if (fileOK)

            {

                try

                {

                    var filePath = path + fileUpload.FileName;

                    fileUpload.PostedFile.SaveAs(filePath);



                    FilePath = filePath;



                    ltrlResult.Text = "File uploaded successfully. Press OK to continue.";

                }

                catch (Exception ex)

                {

                    ltrlResult.Text = "File could not be uploaded.";

                    Sitecore.Diagnostics.Log.Error("File could not be uploaded.", ex, typeof (UploadFile));

                }

            }

            else

            {

                ltrlResult.Text = "Cannot accept files of this type.";

            }

        }



        base.OnLoad(e);

    }



    protected override void OK_Click()

    {

        if (string.IsNullOrEmpty(FilePath))

        {

            SheerResponse.ShowError("You must first upload a file.", string.Empty);

            return;

        }



        SheerResponse.SetDialogValue(FilePath);



        SheerResponse.Alert(

                "The import process is starting. This may take a few minutes. nnPress OK to continue, and wait until the import confirmation popup appears.");





        base.OK_Click();

    }

}

The upload is succeeding, It's setting SheerResponse.SetDialogValue(FilePath), but when I get back into the postback of ImportTrials, args.HasResult is false and args.Result is null
