[API] Inserting new container in a containerlist, doesn't work

[Sebastien Landeau]

Hello, Context : Jahia Version : 4.0.4 build 5822 (bundle with packaged Tomcat) OS : Linux Fedora Core 2 JDK : 1.4.2_05 DB : mySQL I'm trying to build a JSP page to dynamically insert a new Container in a ContainerList (importing content from external data). But it doesn"t work. IN attachment, my JSP page (a modification of the simple template from the corporate samples). What is bad in it ?? THank's a lot.

<%@ include file="include/header.inc"%>
<%@ page import="org.jahia.registries.ServicesRegistry" %>
<!--
        Defining a simple container list to validate document
        importation from batch Java Scriptlet
-->
<content:declareContainerList name="siteFlashes" title="Les flashs du SITE">
        <content:declareField name="title" title="Titre" type="SmallText"/>
        <content:declareField name="content" title="Contenu" type="BigText"/>
        <content:declareField name="image" title="Picto" type="File"/>
</content:declareContainerList>
<!-- End ContainerList declaration -->
