[jira] [Comment Edited] (PDFBOX-2470) Exception in
PDDocument.addSignature(PDSignature sigObject, SignatureInterface
signatureInterface, SignatureOptions options))
[ https://issues.apache.org/jira/browse/PDFBOX-2470?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14194792#comment-14194792 ]

--------------------------------------------------------------
{code}
((COSObject) item).getObject();
{code}
There's no need to do COSObject dereferencing manually, just call getDictionaryObject() instead of getItem().
P.S. We should probably change those comments to English.

> Hi
> I have made the following modifications to avoid ClassCastException or NullPointerException in addSignature(PDSignature sigObject, SignatureInterface signatureInterface, SignatureOptions options) :
> {code}
> // Appearance Dictionary auslesen und setzen
> // MOD_CS
> // PDAppearanceDictionary ap =
> // new PDAppearanceDictionary((COSDictionary)cosBaseDict.getItem(COSName.AP));
> // ap.getDictionary().setDirect(true);
> // signatureField.getWidget().setAppearance(ap);
> COSBase item = cosBaseDict.getItem(COSName.AP);
> if (item instanceof COSObject) {
> item = ((COSObject) item).getObject();
> }
> if (item instanceof COSDictionary) {
> PDAppearanceDictionary ap = new PDAppearanceDictionary((COSDictionary) item);
> ap.getDictionary().setDirect(true);
> signatureField.getWidget().setAppearance(ap);
> }
>
> // AcroForm DefaultRessource auslesen und setzen
> COSBase dr = cosBaseDict.getItem(COSName.DR);
> // MOD_CS
> if (dr != null) {
> dr.setDirect(true);
> dr.setNeedToBeUpdate(true);
> acroFormDict.setItem(COSName.DR, dr);
