---------------------------------------
Summary: PDActionEmbeddedGoTo does not accept a Destination with a
page number or string
Key: PDFBOX-5470
URL: https://issues.apache.org/jira/browse/PDFBOX-5470
Project: PDFBox
Issue Type: Bug
Components: AcroForm
Affects Versions: 2.0.26
Reporter: Gilad Denneboom
Attachments: EmbeddedActionTest-1.java, LinkTest.pdf, StackTrace.txt
According to Table 202 of the PDF 32000-1:2008 specs, the P key under the
Target Directory of an Embedded Go-To Action is an "integer or byte string",
with the following description "If the value is an integer, it specifies the
page number (zero-based) in the current document containing the file attachment
annotation. If the value is a string, it specifies a named destination in the
current document that provides the page number of the file attachment
annotation."
However, the current implementation of PDActionEmbeddedGoTo does not accept
using the setPageNumber command by itself when setting the Destination
dictionary, and throws an IllegalArgumentException unless setPage is used to
set the target page as a PDPage object, which is not specified in the
documentation. Also, there doesn't seem to be a way to specify the target as a
string, if a named destination is to be used.
This applies to both the Destination dictionary and the Target Directory, but
when creating such a link in Acrobat the Target Directory does not contain a P
value at all, only the Destination dictionary does, and in the form of a
number. This should be possible to replicate using PDFBox.
Attached are a sample file with a pre-existing link and a PDF attachment, the
code trying to set that link's action to open the attachment on page 3, and the
resulting error message stack trace.
