Re: Jahia 6 Community Edition - size of a containerList populated by a query

Hello,


the following example shows how to get the size of a container list (no 
matter if it is populated by a query or not - the size property is 
available on  the ContainerListBean instance, exposed into its scope by 
<template:containerList/> tag):

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
...
<template:containerList name="events" id="eventsContainer" 
actionMenuNamePostFix="events"
                        actionMenuNameLabelKey="events" 
sortByField="${sortBy}" enforceDefinedSort="true" sortOrder="${order}">
    <query:containerQuery>
         <query:selector nodeTypeName="web_templates:eventContainer" 
selectorName="eventsSelector"/>
        <query:childNode selectorName="eventsSelector" 
path="${eventsContainer.JCRPath}"/>
            <utility:dateUtil currentDate="${param.startDate}" 
datePattern="dd/MM/yyyy" valueID="today" hours="0"
                              minutes="0"
                              seconds="0"/>
            <query:greaterThanOrEqualTo numberValue="true" 
propertyName="startDate" value="${today.time}"/>
    </query:containerQuery>

    ...
    do display it
    ...
    We have ${eventsContainer.size}events

    <c:if test="${eventsContainer.size > 1}">
          we have multiple events
    </c:if>
    <c:if test="${eventsContainer.size == 1}">
          we have a single event
    </c:if>
    <c:if test="${eventsContainer.size == 0}">
          no events at all
    </c:if>
</template:containerList>


Could you give us, please, the example of code, you are trying to use?

Kind regards
Sergiy
