I've attached the input and output files and the code used to generate is below:
Aspose.Pdf.Kit.License license = new Aspose.Pdf.Kit.License();
license.SetLicense("Aspose.Pdf.Kit.lic");
Aspose.Pdf.Kit.Form pagingForm = new Aspose.Pdf.Kit.Form("sampleIn.pdf", "sampleOut.pdf");
pagingForm.FillField("TextField1", "asdf");
pagingForm.FlattenAllFields();
pagingForm.Save();
The output document displays this message instead of the form. I am using the latest version of Reader 9.1.2.
