[opencms-dev] Contentload problem?

[Jonathan Woods]

Toni -

Sounds like a good solution.  Interesting to note that the <cms:contentinfo>
isn't documented at all, as far as I can tell.

>From digging around in source code, I think the case of the contentinfo var
attribute value may need to be "CollectorInfo".

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.
