I suspect that the feature mentioned is more recent than the modes of PDF that OpenOffice export supports.
By supporting the feature do you mean this: FEATURE REQUEST OpenOffice Writer documents that contain enterable fields should reflect those fields as enterable when exported as PDF when the level of PDF is one in which provision of field entries is allowed and has been selected in the PDF export options. In all other cases, the document is exported to PDF with the current content of the field made part of the text without any presentation as a field. Note 1: This provision is independent of the technique by which the ODT corresponding to the PDF is embedded in the PDF as an attachment and available for extraction and use by a compatible PDF consumer. Note 2: Implementations that convert PDFs to editable form by other than the device in (Note 1) may (but need not) recover enterable fields as such. - Dennis -----Original Message----- From: Peter Eberlein [mailto:pet....@refofd.verwalt-berlin.de] Sent: Friday, February 01, 2013 00:48 To: dev@openoffice.apache.org Subject: pdf export option for FilterData and ExportFormFields Hi, Adobe products support an extended feature, so that Acrobat Reader can store the content of filled fields in forms. Is supporting this feature in openoffice a legal or a technical issue? Supported features see [1]. Regards Peter [1] http://wiki.openoffice.org/wiki/API/Tutorials/PDF_export
