The code below works as far as it goes.
Until we call PDAcroForm.flatten(), the removed PDField is still accessible.
So the correct code is:
COSDictionary formDict = pdAcroForm.getCOSObject();
COSArray formFieldArray = (COSArray)
formDict.getDictionaryObject(COSName.FIELDS);
formFieldArray.removeObject(pdField.getCOSObject());
// other operations . . .
pdAcroForm.flatten();

Subject: Completely Remove a Field
It seems like removing a PDField from a loaded PDDocument would be trivial.
The goal is to remove the field from the form and anything related to that
field from the displayed PDF.
I have tried just removing the PDField from the List of PDAcroForm.getFields()
which does not seem to work.
And I have tried digging into the PDAcroForm's dictionary:
PDField pdField = pdAcroForm.getField("boxAPPL");
COSDictionary formDict = pdAcroForm.getCOSObject();
COSArray fieldz = (COSArray) formDict.getDictionaryObject(COSName.FIELDS);
fieldz.removeObject(pdField.getCOSObject());
which does not appear to work either.
Any is help appreciated.
