51 Adding Messages and Feedback to a Portal

Add Messages and Feedback to a portal to allow portal members to post, view, and manage messages and feedback to and from their connections. .

Permissions:

To perform the tasks in this chapter, you must be a portal manager or a portal member with the portal-level permissions Basic Services: Edit Page Access and Structure (standard permissions) or Pages: Edit Pages (advanced permissions).

See About Roles and Permissions for a Portal.

51.1 About Message Board

On personal pages in the Home portal, Message Board provides a means of viewing and posting messages to and from you and other users. To view your messages, you must add a Message viewer to one of your personal pages (a page you created) in the Home portal. To receive messages from other users, you must provide other users access to that personal page and set your message preferences to allow those users to view and/or post messages for you. To view or post messages for another user, you must be granted access to that user's personal page and access to view and/or post messages for the user through that user's preferences.

In portals other than the Home portal, Message Board provides a means of viewing and posting messages within the scope of the portal. In a portal, every instance of a Message Board task flow shows the same content: messages left by authorized users who are members of the portal. The portal Message Board leverages Page permissions as its permission model.

Table 51-1 lists the page permissions required for performing actions in a portal Message Board.

Table 51-1 Page Permissions for a Portal Message Board

Page Permission	Post	View	Update	Delete
View Page	No	Yes	No	No
Personalize Page	Yes	Yes	Yes for messages posted by this user	Yes for messages posted by this user
Perform All Page Actions	Yes	Yes	Yes for all messages	Yes for all messages

51.2 About Feedback

Feedback provides a means of viewing, posting, and managing feedback remarks. Feedback task flows must be associated with an individual user, so they are meant to be added to a user's personal page in the Home portal. The user can then provide other users access to that personal page so that those users can provide feedback.

WebCenter Portal provides the following Feedback task flows:

Feedback for viewing, posting, and managing Feedback (Figure 51-3)

Description of "Figure 51-3 Feedback Task Flow"
Feedback - Quick View for viewing and posting Feedback (Figure 51-4)

Description of "Figure 51-4 Feedback - Quick View Task Flow"

For more information about Feedback features, see Working with Feedback and the Message Board in Oracle Fusion Middleware Using Oracle WebCenter Portal.

51.3 Adding a Message Board or Feedback Task Flow to a Page

For the steps to add a Message Board or Feedback task flow to a page, see Adding a Component to a Page.

Note:

The presence or location of the Message Board or Feedback task flows in the resource catalog depends on how the resource catalog is configured. For example, in the Default Portal Catalog, the Announcements task flow is Message Board task flows are included under the Social and Communications folder.

The Feedback task flows are not available in the Default Portal Catalog provided with WebCenter Portal, so you will only see an entry for them if they have been added to a custom resource catalog that has been made available to the page.

For more information, see Adding a Resource from the Resource Registry (in the Add Resource Catalog Item dialog, select Task Flows, then Design Time, then scroll to the Feedback task flows). To use the custom resource catalog for editing portal pages, make sure it is Available, and set for use by pages in the portal, as described in Changing the Resource Catalogs in a Portal.

51.4 Working with Message Board and Feedback Task Flow Properties

Note:

The Feedback task flows are meant for a user's personal page because they must be associated with an individual user. However, working with task flow properties is an advanced task and is therefore covered in this guide rather than in Oracle Fusion Middleware Using Oracle WebCenter Portal.

Message Board and Feedback task flows have associated properties that users with sufficient privileges can access through the task flow's View Actions menu. For example, in edit page mode, click the task flow to show the View Actions menu, and select Parameters to open the Parameters dialog (Figure 51-5).

Figure 51-5 Parameters Dialog for a Feedback Task Flow

Description of "Figure 51-5 Parameters Dialog for a Feedback Task Flow"

The following sections provide information about Message Board and Feedback task flow properties and describe task flow parameters:

Note:

For more information, see Setting Properties on a Component.

51.4.1 Setting Message Board and Feedback Task Flow Properties

In the page editor, selecting any component exposes a View Actions menu (Figure 51-6), which provides access to the component’s properties: Parameters, Access, Display Options, Style, and Content Style.

Figure 51-6 View Actions Menu on a Message Board Task Flow

Description of "Figure 51-6 View Actions Menu on a Message Board Task Flow"

To set Message Board or Feedback task flow properties:

Open the page that contains the task flow in the page editor (see Opening a Page in the Page Editor).
Select the task flow, then click the View Actions menu and select the properties you want to set:
- Parameters control the default task flow content. For descriptions of each parameter, see Message Board and Feedback Task Flow Parameters. Parameters can be wired to events, and can be used facilitate the wiring of the task flow to page parameters and page definition variables. For more information, see Wiring Pages and Components.
- Access settings show or hide the component to specific roles, users, or groups. For more information, see Setting Component Access.
- The Display Options, Style, and Content Style properties affect the appearance and behavior of the task flow for all users. These properties are common to all task flows. For more information, see Modifying Component Properties.
The Parameters and Display Options dialogs provide access to an Expression Language (EL) editor, which you can use to select or specify a variable value instead of a constant value. Click the icon next to a property, then select Expression Builder to open the editor.

Note:

When you enter EL in the Display Options dialog, the parser reports an error only if it detects invalid syntax, such as a missing closing bracket. Validation is performed only on syntax, not on the expression value. Generic Display Options are those cataloged in Table 10-1.

EL validation is not performed on non-generic display options.

If you need EL assistance, an application developer can provide an EL expression; see Expression Language Expressions in Oracle Fusion Middleware Developing WebCenter Portal Assets and Custom Components with Oracle JDeveloper.
Save your changes.
