Hello,

here is our code for generating documents:

public class BobTheBuilder
{
    public void GenerateReport(byte[] inputTemplate, string outputDocument, object data, SaveOptions saveOption)
    {
        using (var inputTemplateStream = new MemoryStream(inputTemplate))
        using (var tmpDocumentStream = new MemoryStream())
        using (var outputDocumentStream = new FileStream(outputDocument, FileMode.Create))
        {
            this.GeneratePdfReport(inputTemplateStream, tmpDocumentStream, data, saveOption);

            var document = Document.Load(tmpDocumentStream);
            document.Save(outputDocumentStream, saveOption);
        }
    }

    private void GeneratePdfReport(Stream template, Stream report, object data, SaveOptions saveOption)
    {
        var documentGenerator = new DocumentGenerator(data);

        documentGenerator.ElementInitialize += this.DocumentGeneratorOnElementInitialize;

        var result = documentGenerator.GenerateDocument(template, report, saveOption);

        if (!result.HasErrors) return;

        foreach (var error in result.Errors)
        {
            Console.WriteLine(error);
        }
    }

    private void DocumentGeneratorOnElementInitialize(object sender, ElementInitializeEventArgs elementInitializeEventArgs)
    {

    }
}

The suggested workaround to update the Table of Contents in the document is to load the generated Document and Save it using the Document.Load() and Document.Save().

However this line:

 var document = Document.Load(tmpDocumentStream);

causes the following exception: (formatting is a bit weird, sorry about that)

System.Exception was unhandled by user code HResult=-2146233088
Message=Style 'Normal' cannot be added to the document because a style with the same name already exists in the document.
