Hello, i tried to implement the component example http://extensions.xwiki.org/xwiki/bin/view/Extension/WikiComponent+Module which is also available from https://github.com/jvdrean/xwiki-proverb-example When i put the compiled jar at WEB-INF/lib i get after starting the server org.xwiki.query.QueryException: Exception while execute query. Query statement = [ select doc.space , doc.name from XWikiDocument as doc , BaseObject as proverb where ( proverb.proverb <> '' ) and doc.fullName=proverb.name and proverb.className='XWiki.Proverb' ] ... "Caused by: com.xpn.xwiki.XWikiException: Error number 0 in 3: Exception while hibernate execute Wrapped Exception: could not resolve property: proverb of: com.xpn.xwiki.objects.BaseObject [ select doc.space , doc.name from com.xpn.xwiki.doc.XWikiDocument a s doc , com.xpn.xwiki.objects.BaseObject as proverb where ( proverb.proverb <> '' ) and doc.fullName=proverb.name and proverb.className='XWiki.Proverb' ] I use XWIKI v5.1 with embedded HsqlDB on Windows7. I dont get whats wrong and really appreciate some hints. My goal is to all new classes to a document or new properties to a page, but even get this example. Has anyone an idea what i did wrong?
