public class TagHead

extends javax.servlet.jsp.tagext.TagSupport

This tag is required before any other NuContent tags. It does the following:

1. Performs page-level authorization
2. Sets default template ID. All tags will accept a templateId parameter, but will revert to the default template ID set here.
3. Adds Page object to request object to be accessed later by other tags
4. Adds various useful variables to the current pageContext, which are described below

The followng variables are set in the current pageContext. The boolean variables start with "pageIs..." and are either set to "1" if they are true, or not set (null) if false:

• pageIsEditable is true if the current user has permission to edit the page. Note that it is still true if the user is currently locked out of editing.
• pageIsLockable is true if locking is active for the page, either by setting this tag's lockable property to "true" or if the site property requireLocking is set to "true"
• pageIsLocked is true if the current page is lockable, the current user has permission to edit it, and if it is actually locked by someone.
• pageIsLockedByCurrentUser is true if the current page is lockable, and locked by the current user.
• userVO
represents the current user.
