[opencms-dev] Contentload problem?

[Toni Pérez]

Hi, Gunther.

You could try this:

<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms" %>
<%@ taglib prefix="c"   uri="http://java.sun.com/jstl/core" %>

<% int jobCount = 0; %>

<cms:contentload collector="allInFolderDateReleasedDesc"
param="/jobs/job_${number}.html|123" editable="true">

	<cms:contentinfo var="collectorInfo" scope="page" />
	
	<c:if test="${! pageScope.collectorInfo.emptyResult}">
		<% jobCount++; %>
	</c:if>
	
</cms:contentload>

<%= jobCount %>


The code was written on-the-fly so it could not compile.

I hope that helps.

PS.: this question is a frequently asked question on the list. I think
it would be a good idea to include a couple of lines in the
documentation of the "contentload" tag.
