Bug Report
Hello, I had many problems with version 2023.1.117, latest stable 2023.2.606 is unusable also due to issue with scanned documents etc, so I tried 2020.2.703-hotfix, but I am getting other set of issues.
Unfortunately I cannot share the documents, since they are confidential.
With some documents I am getting this error:
Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfName' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Objects.FormXObject'.
Loading Code:
PdfFormatProvider pdfFormatProvider = new();
RadFixedDocument document = pdfFormatProvider.Import(bytes);
And stack trace:

When importing specific documents and signing a predefined SignatureField leads to not successfully validated signatures in Adobe, but successfully validated in other pdf viewers (eg. Telerik WPF PdfViewer, Foxit PDF Reader).
Solution:
When signing an existing document (after the import) we must be sure the AcroForm's ViewersShouldRecalculateWidgetAppearances property is set to false, otherwise, the exported and signed PDF document could not be shown as a signed.
if (document.AcroForm.ViewersShouldRecalculateWidgetAppearances)
{
document.AcroForm.ViewersShouldRecalculateWidgetAppearances = false;
}
