[xwiki-devs] Problem obtaining external URL from XWikiDocument in servlet deployment

Hi, I'm writing an indexer plugin for XWiki and recently found a problem when trying to obtain the external document url: java.lang.NullPointerException at com.xpn.xwiki.XWiki.getServletPath(XWiki.java:4317) at com .xpn .xwiki .web.XWikiServletURLFactory.addServletPath(XWikiServletURLFactory.java: 208) at com .xpn .xwiki .web.XWikiServletURLFactory.createURL(XWikiServletURLFactory.java:178) at com .xpn .xwiki .web .XWikiServletURLFactory.createExternalURL(XWikiServletURLFactory.java: 273) at com.xpn.xwiki.doc.XWikiDocument.getExternalURL(XWikiDocument.java: 925) at com .kontrast .vodafone .portal .xwiki.plugins.indexer.IndexUpdater.runMainLoop(IndexUpdater.java:180) at com .kontrast .vodafone .portal.xwiki.plugins.indexer.IndexUpdater.run(IndexUpdater.java:116) I updated to XWiki version 1.7-SNAPSHOT recently. Before that I didn't experience this. Can anyone shed some light on this? Thanks, J.L.Simon
