This chapter includes the following topics:
To perform the tasks in this chapter, you must be a portal manager or a portal member with the portal-level permission
Basic Services: Edit Page Access, Structure, and Content (standard permissions) or
Pages: Edit Pages (advanced permissions).
For more information about permissions, see About Roles and Permissions for a Portal.
WebCenter Portal provides two portal task flows that you can add to a page:
Portal Members task flow: Shows the portal members and provides controls to add new members, send a mail message to all members, filter the list by role, and search for members. For more information about this task flow, see Working with the Portal Members Task Flow.
Portal Browser task flow (Figure 7-1): Adds an area that operates identically to the portal browser, providing users with the ability to work with their portals on the page, rather than navigating to portal browser. For information about working with this task flow, see Viewing and Accessing Available Portals in Using Oracle WebCenter Portal.
Figure 7-1 Portal Browser Task Flow
Adding a Portal Browser task flow to a page is the same as adding any other component to a page. See Adding a Component to a Page.
The Portal Browser task flow is not available in the Default Portal Catalog provided with WebCenter Portal, so you will only see an entry for it if it has 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 Portal Browser). 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.
The Portal Browser task flow has associated properties, which users with sufficient privileges can access through the task flow's View Actions menu. For example, select Parameters to display the Parameters dialog (Figure 7-2).
Figure 7-2 Portal Browser Task Flow Component Properties
The following sections provide information about properties of the Portal Browser task flow and describe the task flow parameters:
In the page editor, the View Actions menu in the toolbar of the Portal Browser task flow (Figure 7-3) provides access to the properties dialogs: Parameters, Access, Display Options, Style, and Content Style.
Figure 7-3 Portal Browser Component Toolbar: View Actions Menu
To set the Portal Browser component properties:
Parameters control the default task flow content. For descriptions of each parameter, see Portal Browser 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.
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 Developing WebCenter Portal Assets and Custom Components with Oracle JDeveloper.
Table 7-1 describes the parameters that are unique to the Portal Browser task flow.
