On the attached file I am attempting to update the first link on this page. After setting the DestinationFile Property on the LaunchAction and calling savechanges the library is throwing the exception:
The exact exception is in my original post.
Dim myPage As Aspose.Pdf.Page = pdfDoc.Pages(1)
Dim myLinkAnnot As Aspose.Pdf.InteractiveFeatures.Annotations.LinkAnnotation = myPage.Annotations(1)
Dim myGotoAction As Aspose.Pdf.InteractiveFeatures.LaunchAction = myLinkAnnot.Action
Thanks for providing additional information, I've managed to reproduce the issue at my end and logged it as PDFNEWNET-35019 in our issue tracking system for further investigation and resolution. We will keep you updated regarding issue status via this thread.
Sorry for the inconvenience faced.
