Description

It would be really nice to be able to access resources through tags rather than having to use Scriptlet for even basic Resource iteration. I've created a patch for adding tags to:

• Get a Resource
• List Child Resources
• Adapt adaptables to other classes
• Get properties from ValueMaps (with default values)

With these new tags, you will be able to do things like create an entire navigation without scriptlet:
<ul>
<sling:getResource var="currentResource" path="/libs" />
<sling:listChildren var="children" resource="${currentResource}" />
<c:forEach var="child" items="${children}">
<c:if test="${child.name != 'jcr:content'}">
<sling:getResource var="pageContent" path="${child.path}/jcr:content" />
<sling:adapt adaptable="${pageContent}" adaptTo="org.apache.sling.api.resource.ValueMap" var="childProperties" />
<sling:getProperty key="jcr:title" defaultValue="${child.name}" var="title" properties="${childProperties}" />
<li><a href="${child.path}.html">Title: ${title}</a></li>
</c:if>
</c:forEach>
</ul>
