Tilman Hausherr commented on PDFBOX-6179:
-----------------------------------------
I've now tested my code on a file with a real multilevel field tree (the first
file from PDFBOX-2469) and the code works, however one would have to add
{{doc.setAllSecurityToBeRemoved(true);}} and
{{doc.getDocumentCatalog().getCOSObject().removeItem(COSName.PERMS);}} before
saving.
I could add this to the examples codes but only if you'd tell me a real world
use case for that.
> Removing fields not possible
> ----------------------------
>
> Key: PDFBOX-6179
> URL: https://issues.apache.org/jira/browse/PDFBOX-6179
> Project: PDFBox
> Issue Type: Bug
> Components: AcroForm
> Affects Versions: 3.0.7 PDFBox
> Reporter: Stefan Ziegler
> Priority: Major
> Attachments: simple_form.pdf
>
>
> Seems that fields can no longer be removed like this:
> PDField field = acroForm.getField("XXXXX");
> List<PDField> fields = acroForm.getFields();
> fields.remove(field);
> Internally, the field is never found. PDField has no equals method. getField
> and getFields create new PDField instances and so equals fails in this case.
> Shouldn't there be an equals method in PDField, that compares the underlying
> COSObject?
