Hi, This is because the headings get an ID based on the heading text, which is unique inside a document. Given that you are including more than one document in the same pdf, the unique constraint is no longer satisfied. This is a bug and should be reported on http://jira.xwiki.org/ Sergiu Raffaele Viola wrote:
Hi all,
I chenged in the file menuview.vm the row: #submenuitem($doc.getURL("export", "format=pdf&$docvariant") $msg.get("core.menu.export.pdf")) in #submenuitem($doc.getURL("export", "format=pdf&includechilds=1&$docvariant") $msg.get("core.menu.export.pdf"))
to include childs pages into PDF export but when I try to execute export in PDF I get this exception
com.xpn.xwiki.XWikiException: Error number 12002 in 12: Exception while exporting PDF Wrapped Exception: org.apache.fop.fo.ValidationException: null:118:234: Property id "HInventory" previously used; id values must be unique in document. at com.xpn.xwiki.pdf.impl.PdfExportImpl.exportXMLFO(PdfExportImpl.java:194) at com.xpn.xwiki.pdf.impl.PdfExportImpl.exportXHtml(PdfExportImpl.java:134) at com.xpn.xwiki.pdf.impl.PdfExportImpl.exportHtml(PdfExportImpl.java:202) at com.xpn.xwiki.pdf.impl.PdfExportImpl.export(PdfExportImpl.java:225) at com.xpn.xwiki.web.ExportAction.exportPDFOrRTF(ExportAction.java:198)
It seems the validator has problems parsing the link in the text created joining the parent with childs pages.
Thanks raffo
