Package nl.gx.webmanager.taglib.edit

Class RenderTag

java.lang.Object

javax.servlet.jsp.tagext.SimpleTagSupport

nl.gx.webmanager.taglib.edit.RenderTag

All Implemented Interfaces:

javax.servlet.jsp.tagext.DynamicAttributes, javax.servlet.jsp.tagext.JspTag, javax.servlet.jsp.tagext.SimpleTag

public class RenderTag
extends javax.servlet.jsp.tagext.SimpleTagSupport
implements javax.servlet.jsp.tagext.DynamicAttributes

Implements the wmedit:render tag.

  <wm:render var="headTag" presentationName="WM custom head tag" />
  <wm:render var="bodyTag" presentationName="WM custom body tag" />
 

In the example above a custom head tag and body tag for a page are rendered using two different presentations. In this case the default presentation of the content item is not used because the optional presentationName is provided in the < wm:render > tag. Additionally, no object is specified which means that the object which is being rendered is the same as the object that is rendered by the jsp this code is in. The example renders both the head and body tag into separate variables. You can also explicitly specify an object and no presentation. This is done in content.jspf, for example:

    <wmedit:render object="${element}" />
 

This render tag renders the object ${element} (the jsp loops over all page elements) with whatever presentationname is associated with the object in GX WebManager.
