[xwiki-users] pdf export issue

Hi, I've got the following problem when exporting to PFD/RTF: exporting a full space as PDF/RTF, specifying the top-level space including the children (http://localhost:8080/mywiki/bin/export/Sandbox/?format=pdf&includechil…)s=2), generates the following error: Some extra information: Error number 11015 in 11: Exception while exporting Wrapped Exception: Error number 12002 in 12: Exception while exporting PDF Wrapped Exception: org.apache.fop.fo.ValidationException: "fo:list-block" is missing child elements. Required content model: marker* (list-item)+ (See position 320:90) com.xpn.xwiki.XWikiException: Error number 11015 in 11: Exception while exporting Wrapped Exception: Error number 12002 in 12: Exception while exporting PDF Wrapped Exception: org.apache.fop.fo.ValidationException: "fo:list-block" is missing child elements. Required content model: marker* (list-item)+ (See position 320:90) at com.xpn.xwiki.web.ExportAction.render(ExportAction.java:67) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:214) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:115) It appears that this results from including the WebPreferences page, which is also a child. Exporting the WebPreferences page alone generates the same error. So I removed the parent link of the WebPreferences page (which is now orphaned), and then the export works perfectly well. Two questions: 1-Is it possible to solve this bug? 2-Does it harm in any other way when I remove the parent link of a WebPreferences page? This would be a fine workaround if allowed. Regards, Wouter
