Example odt document that exhibits the issue when exported to PDF
I have discovered that large odt documents (>~500) that are exported to PDF
format, often have these PDF-syntax errors reported by PAC2024 accessibility
checker:
"Structure element refers to a different parent than the actual parent"
The beginning of the document never has these errors, but after certain point
every paragraph has this error. If you divide the document to smaller sections
(https://help.libreoffice.org/latest/en-US/text/swriter/guide/sections.html),
this problem goes away. Same thing happens also if you just cut enough content
away.
To me this behaviour sounds like some kind of index has run out of numbers and
no more children can be added.
A good example of this is the "Useful Macro Information For OpenOffice.org" By
Andrew Pitonyak, which I will attach to this bug report. If you export this
document to PDF and run it through PAC 2024, it will report the previously
mentioned issues. I will also add the exported PDF file to this bug report.
I will also attach a version of this document, where I have assigned all
Chapters 1-20 to their own sections. This version does not suffer from the
previously mentioned issue, if you run a PDF export of this file through PAC
2024. I will attach the said PDF-file.
I will also add a screenshot of the PAC 2024 errors to this issue.
I tested this issue with LO 25.2.4.3 (X86_64) and LO 7.0.6, which both produce
the same errors.
