Re: Error trying to create PDF with accessibility

Hi Esteban,

It seems like an XML parsing error. Have you checked your FO file
is well-formed? (Rename extension to XML and Open it in a browser
ie: firefox or chrome)

Hello I'm working in a quite complex java (1.8.0_112) project,
using apache-fop 2.2. Windows 10 OS.

It seems that the <accessibility> tag is ignored in the
xconf file so I had to enable it programatically.

After that, I get the following exception when rendering pdf
with accessibility enabled:

java.lang.NullPointerException

fatalError

GRAVE: org.xml.sax.SAXParseException; systemId:
file:///C:/Users/complete_file_name.fo ; lineNumber: 160;

The above-mentioned line 160 is:

<fo:page-sequence master-reference="onlySeq"

Maybe I'm missing something? I may try to create a full
example if needed.
