Hi,
if I recall correctly, then you should generate/update appearance
streams of the modified fields too. Those are used to show the content
of the field when the field is not focused (apart of other usages). The
behavior also depends on the AcroForm's NeedAppearances flag
(PdfAcroForm::GetNeedAppearances() / SetNeedAppearances()), when it's
'false', the appearance streams are generated by the PDF reader.
Bye,
