User Customizations

User customizations or change persistence allow end users to make changes to certain UI components at runtime to suit individual preferences (for example, the user can decide which columns are visible in a table). There are two types of user customizations:

• Those that stay in place through the length of the user's session until the user exits the application
• Those that are permanently stored in a repository and are restored whenever the user reenters the application

In this step you are enabling user customizations for the length or duration of a session.

When you enable session user customizations, JDeveloper adds the following context initialization parameter into web.xml:

                               
<context-param>
  <param-name>org.apache.myfaces.trinidad.CHANGE_PERSISTENCE</param-name>
  <param-value>session</param-value>
</context-param>
                            

The value of CHANGE_PERSISTENCE is set to session for session change persistence.
