Re: jahia_calendar default value

Hello,

You can use an eventlistner to set a default value if no value has 
been set in the engine. Here is an example where the value set is the 
actual time.

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ page import="java.util.*" %>
<%@ page import="org.jahia.content.*" %>
<%@ page import="org.jahia.data.*" %>
<%@ page import="org.jahia.data.containers.*" %>
<%@ page import="org.jahia.data.fields.*" %>
<%@ page import="org.jahia.data.events.*" %>
<%@ page import="org.jahia.engines.*" %>
<%@ page import="org.jahia.engines.categories.*" %>
<%@ page import="org.jahia.engines.selectpage.*" %>
<%@ page import="org.jahia.engines.shared.*" %>
<%@ page import="org.jahia.params.*" %>
<%@ page import="org.jahia.registries.*" %>
<%@ page import="org.jahia.services.categories.*" %>
<%@ page import="org.jahia.services.containers.*" %>
<%@ page import="org.jahia.services.database.*" %>
<%@ page import="org.jahia.services.fields.*" %>
<%@ page import="org.jahia.services.pages.*" %>
<%@ page import="org.jahia.services.version.*" %>
<jsp:useBean id="eventsToTrap" class="java.util.Vector" scope="application"/>
<%// loads the events to trap
if (eventsToTrap.size() == 0) {
         eventsToTrap.add("addContainerEngineAfterInit");
         eventsToTrap.add("addContainerEngineBeforeSave");
         eventsToTrap.add("containerAdded");
         eventsToTrap.add("containerUpdated");
}

String eventName = (String) request.getAttribute("eventName");
JahiaEvent jahiaEvent = (JahiaEvent) request.getAttribute("jahiaEvent");
ParamBean jParams = jahiaEvent.getParams();

if ( eventsToTrap.contains(eventName)){
         HashMap engineMap =
             (HashMap) jParams.getSession().getAttribute( 
"jahia_session_engineMap" );
         if (engineMap == null) { return; }
         String languageCode = (String)engineMap.get("languageCode");
         HashSet updatedFields = (HashSet)engineMap.get("updated.fields");
     if (updatedFields == null) {
             updatedFields = new HashSet();
             engineMap.put("updated.fields", updatedFields);
         }
         JahiaContainer theContainer = (JahiaContainer)jahiaEvent.getObject();

     if ( "yourContainer".equals(theContainer.getDefinition().getName()) ){
         if ( "addContainerEngineAfterInit".equals(eventName) ) {
             JahiaField theField = theContainer.getField("yourDate");
             if (theField.getObject() == null) {
                 Calendar cal = 
Calendar.getInstance(TimeZone.getTimeZone("UTC"));
                 long now = cal.getTime().getTime();
                 String nowStr = String.valueOf(now);
                 theField.setObject(nowStr);
                 updatedFields.add(new Integer(theField.getID()));
             }
         }
     }
}
%>

Cheers,

Philippe.
