Hi list,When I generate a FO file from the following XML, the transformation into a PDF file using FOP throws a java.lang.NullPointerException. I am unable to determine the cause of the problem. If I remove the <anchor xml:id="testid" /> element, things are working fine. I tried to setup a minimal FO file with the code generated by the anchor, but, surprisingly, the PDF is generated fine from this file. Note that I sent to FOP mailing list a copy of the stack trace. Maybe you can help me with that?I have the same result with versions 1.75.2 and 1.76.0 of the style sheets and versions 0.95 and 1.0 of FOP.Thanks a lot! <?xml version="1.0" encoding="UTF-8"?><section
