Now my objects are persistents. But i don't know how to access their properties. Should i create an annotation class through the XWiki class editor? It seems that in my database, none of the properties of my annotations are stored. I define an annotation for a document: $xwiki.annotation.addNewAnnotation($doc,"blablablaAnnotation",0,10,"blablaSelection","auteur") I retrieve all annotations of a document: #set($annots=$doc.getObjects("annotation")) And i try to get the selection field of my annotations: #foreach($annot in $annots) "$annot.get("selection")" #end But all i have is "". What should i do? -- Antoine SEILLES Doctorant (phd student) Pikko software Cap Omega - Rond Point Benjamin Franklin CS 39521 34960 Montpellier Cedex 2 FRANCE LIRMM CNRS UMR 5506 - 161 rue Ada 34392 Montpellier Cedex 5 FRANCE Tel: +33 (0)6 10 192 055 http://www.pikko-software.com http://www.lirmm.fr
