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.*" %>

<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()));
}
}
}
}

Hi all,
This example has been tried with Jahia 4.0.4.
I'm trying to set a default value to a jahia calendar as follows:
java.text.DateFormat dateFormat = new
java.text.SimpleDateFormat("dd MMM yyyy / HH:mm");
String publicatieDatum = "<jahia_calendar[dd mon yyyy / HH:MM]>"
+ dateFormat.format(new Date());
So, the string will look like:
"<jahia_calendar[dd mon yyyy / HH:MM]>21 Dec 2005 / 14:48"
This should be possible according to the following description:
A special tag ("<jahia_calendar[DateFormat]>") to set the date format,
followed by a default value.
In fact, I *do* see the default value in the date field, however, it is
not stored (the date is the publication date of an article).
Do I do something wrong, or is this a bug in Jahia?
thanks,
Hilbert
