[jira] [Commented] (PDFBOX-3667) Handle Widget Annotations as Fields even if there is no AcroForm Fields entry

To deal with the situation there are two possible options IMHO
a) to provide a handling similar to Adobe Acrobat add a {{getFields}} method at the {{PDDocument}} level which will use the {{PDAcroForm}} field information if available and if not use the {{PDAnnotation}} information.
b) build an {{AcroForm}} and {{Fields}} entry from the {{PDAnnotation}} information

a) would allow to handle it like Adobe does. b) will fix the broken information and add the necessary entries, but it will also change the model we have for the PDF. 

My preference here would be a). 

Thinking a little more about it IMHO the best option would be to add a layer on top of our current model and use a new tool, service, util what ever you'd like to call it. {{FormManager(PDDocument)}} which will sit on top and handle forms related stuff. Will have the added benefit that we can implement our default appearance when creating a new field. As this is implementation specific and not part of the PDF spec we will keep that separate from the specified stuff and don't clutter or add a lot of new stuff to the existing classes.

WDYT?

> Some (mostly older) files have Widget Annotations but there is no AcroForms/Fields entry. PDFBox doesn't recognize these as form fields where Adobe Acrobat recognizes handles that. For a sample see PDFBOX-2003 and PDFBOX-3586.
