[opencms-dev] How to know the contentload result size prior to looping?

[Mathias Lin | SYSVISION]

One way would be using the contentload-tag to do the counting before hand:

<c:set var="cnt" value="0"/>
<cms:contentload collector="allInFolder" param="${philosophiesPath}|
philosophy"><c:set var="cnt" value="${cnt++}"/></cms:contentload>

Then you can do the check...
<c:if test="${cnt ge 1}"> ... </c:if>

But note: it occurs to me that there's a bug in the contentload/loop when
there are no elements in the folder and you activate direct edit. The
contentload loop always counts 1, regardless whether there is one or none
element found in a folder.
This problem has been reported before in the mailing list and we came across
it as well in a recent project, seems like a bug to me. Not sure if it's
been fixed in 7.5 already.
