Using Umbraco version 7.5.2; Umbraco Forms: 4.3.2

Hello everyone.

I want to make a workflow where i force the user to download a file. But if i use response.TransmitFile(xxx), then it stops the form process and never gets completed. (but the file is bein downloaded).

I made a workflow where the user can select a file from the media library. And that returns a url. (So i convert it to a File.)

public override WorkflowExecutionStatus Execute(Record record, RecordEventArgs e)
{
    if (!string.IsNullOrEmpty(ChoosenFile))
    {
        var filePathAndName = HostingEnvironment.MapPath("~" + ChoosenFile);
        if (!string.IsNullOrEmpty(filePathAndName))
        {
            var file = new FileInfo(filePathAndName);
            var response = HttpContext.Current.Response;
            response.AppendHeader("Content-Disposition", "attachment; filename=" + file.Name);
            response.AppendHeader("Content-Length", file.Length.ToString());
            response.ContentType = ContentHelper.ReturnExtension(file.Extension.ToLower());
            response.TransmitFile(file.FullName);
            response.End();

            return WorkflowExecutionStatus.Completed;
        }
    }

    return WorkflowExecutionStatus.Failed;
}

It downloads the file, but stop the form progress.. I hope someone knows what to do ;)
