Subject [jira] [Commented] (PDFBOX-4408) Object StructParent property does not match entry in parent tree
Date Tue, 18 Dec 2018 19:41:00 GMT

Dan Anderson commented on PDFBOX-4408:
--------------------------------------

The experimenting I've done shows that it doesn't care if the numbers have gaps, only that
the key matches the StructParent property.

> After merging 2 documents together, the parent tree entries for the second page do not
match their expected key.  For the attached document you can look at the "Date you are available"
field after the merge.  In the parent tree the second page field is located with key of 15. 
However the object expects its key to be 21.  The /StructParent value is 21 but it should
be 15.  This mismatch causes issues with a11y readers and the reading order in Adobe DC.
>  
> The fields brought from the destination document are correct, but fields from the source
document do not match.  They continue with the pattern, so the next field is located at key
16 but the /StructParent value is 22, 17 for 23, etc.
