Intended Audience

The content of this chapter is intended for users with at least the Manage Content privilege on the pages they will work with. To work with Portal Templates, the Manage Template privilege is required on the page group. If a particular task requires, or can be performed under, different privileges, those privileges will be listed before the steps of that task. For more information on page privileges, see Section B.3, "Page and Tab Privileges".

For page groups, parameters and events are enabled by default. For more information, see Chapter 4, "Working with Page Groups". For information on how to add parameters and events to portlets, see the Oracle Fusion Middleware Developer's Guide for Oracle Portal available on the Oracle Portal documentation page of the Oracle Technology Network at http://www.oracle.com/technology/products/ias/portal/documentation.html.
