> Problem when merging PDF 1.4 and PDF 1.1 Documents
> --------------------------------------------------
>
> Key: PDFBOX-4204
> URL: https://issues.apache.org/jira/browse/PDFBOX-4204
> Project: PDFBox
> Issue Type: Bug
> Components: Parsing
> Affects Versions: 2.0.9
> Reporter: Christian Lauer
> Assignee: Tilman Hausherr
> Priority: Major
> Fix For: 2.0.10, 3.0.0 PDFBox
>
>
> Merging PDF 1.1 document with other Version (i.e. PDF 1.4) ends up with following exception: java.io.IOException: Unknown OpenAction COSInt\{26}.
> Here's the referring stack trace
> {code:java}
> Alias: PBOX000029: Enter the username: [guest] java.io.IOException: Unknown OpenAction COSInt{26}
> at org.apache.pdfbox.pdmodel.PDDocumentCatalog.getOpenAction(PDDocumentCatalog.java:279)
> at org.apache.pdfbox.multipdf.PDFMergerUtility.appendDocument(PDFMergerUtility.java:348)
> at org.apache.pdfbox.multipdf.PDFMergerUtility.mergeDocuments(PDFMergerUtility.java:263)
> {code}
>
> To fix this issue COSInteger should be handled in PDDocumentCatalog's getOpenAction method. Our tests showed that returning “null” results in correctly merged document.
> Here is our suggestion for the fixed method:
> {code:java}
> public PDDestinationOrAction getOpenAction() throws IOException {
> COSBase openAction = this.root.getDictionaryObject(COSName.OPEN_ACTION);
> if (openAction == null) {
> return null;
> } else if (openAction instanceof COSBoolean) {
> if (!((COSBoolean) openAction).getValue()) {
> return null;
> } else {
> throw new IOException("Can't create OpenAction from COSBoolean");
> }
> } else if (openAction instanceof COSInteger) {
> return null;
> } else if (openAction instanceof COSDictionary) {
> return PDActionFactory.createAction((COSDictionary)openAction);
> } else if (openAction instanceof COSArray) {
> return PDDestination.create(openAction);
> } else {
> throw new IOException("Unknown OpenAction " + openAction);
> }
> }
> {code}
