Can't add document-level Javascript to a PDF

Aspose.PDF Product Family
1

Hello, using Aspose.PDF .NET 19.12, I’m trying to add document-level Javascript to a PDF. Here is the code:

using (Document document = new Document(new FileStream(path, FileMode.Open, FileAccess.ReadWrite)))
{
	document.JavaScript["hello"] = "function hello(){ app.alert('hello world'); }";
	document.Save();
}

And here is the error I get:

System.InvalidOperationException
  HResult=0x80131509
  Message=Value could be added only to leaf
  Source=Aspose.PDF
  StackTrace:

If I have some existing Javascript in the document, Aspose.PDF will add the hello script correctly, but not if I am adding new document-level Javascript to the document.

The PDF is a simple form with an input text field and a digital signature.

Thank you for contacting support.

Would you please try below code snippet and then share if it suites your requirements.

Aspose.Pdf.Document doc = new Aspose.Pdf.Document(dataDir + "test_sign.pdf");
doc.OpenAction = new Aspose.Pdf.Annotations.JavascriptAction("app.alert('hello world');");
doc.Save(dataDir + "yazdir_19.12.pdf");

I did try that but unfortunately it does not fulfill my requirements. I need to create a document-level function that I can call later on from an Adobe Reader plugin, not a Javascript action that executes on an event.
