[opencms-dev] nullpointer exception while usingcontentloadonempty folder

[David García González]

Hi list!
When I am using the contentload tag and I don't have any structured content to show, how could I show the button to add a new one? It doesn't appear.
Thanks!

Hi list,
Try with this:

<cms:contentload collector="allInFolder" param="/|article">

	<cms:contentinfo var="infoCollector" />

	<c:if test="${infoCollector.resultSize le 0}">
		<p>La lista está vacía</p>
	</c:if>

	<c:if test="${infoCollector.resultSize gt 0}">
		<p><cms:contentshow element="Title" /></p>
	</c:if>

</cms:contentload>

Thanks to Toni!

Rene -

The contentcheck tag is meant to help you here.  Documentation at
/alkacon-documentation/documentation_taglib/docu_tag_contentcheck.html (if
you've installed the Alkacon documentation module).
