javax.faces.view.facelets.TagHandler

org.nuxeo.ecm.platform.ui.web.tag.handler.RepeatTagHandler

All Implemented Interfaces:

javax.faces.view.facelets.FaceletHandler

public class RepeatTagHandler
extends javax.faces.view.facelets.TagHandler

Repeat handler, similar to the standard ForEach handler.

This component encapsulates a c:forEach tag inside a nxu:set tag, to be able to control when the sub-components should be re-created in the case of an ajax re-render.
