This chapter describes how to add a Portal Browser task flow to a page, and how to work with the task flow.
This chapter includes the following topics:
To perform the tasks in this chapter, you must be a portal moderator or a portal member with the portal-level permission
Basic Services: Edit Page Access, Structure, and Content (standard permissions) or the
Pages: Edit Pages (advanced permissions).
For more information about permissions, see Section 29.1, "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 Chapter 31, "Working with the Portal Members Task Flow."
Portal Browser task flow (Figure 11-1): Adds an area that operates identically to the Portals page (portal browser) in the Home portal, providing users with the ability to work with their portals on the page, rather than navigating to the Portals page. For information about working with this task flow, see the "Viewing and Accessing Available Portals" section in Oracle Fusion Middleware Using Oracle WebCenter Portal.
Figure 11-1 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 Section 14.2, "Adding a Component to a Page."
The Portal Browser task flow is not available in the default resource catalog provided out-of-the-box with WebCenter Portal, so you will only see an entry for it if it has been added to the resource catalog that has been made available to the page.
For more information, see Chapter 23, "Working with Resource Catalogs", specifically Section 23.5.1, "Adding a Resource to a Resource Catalog" (in the Add Resource Catalog Item dialog, select Task Flows, then scroll to Portal Browser). Once you have added a task flow to a custom resource catalog, you need to make the resource catalog Available, then make it active for pages in the portal, as described in Section 7.3.5, "Changing the Resource Catalogs for Pages and the Page Template for a Portal."
The Portal Browser task flow has associated properties, which users with sufficient privileges can access through the Component Properties dialog in Composer (Figure 11-2).
For information about accessing the Component Properties dialog, see Section 14.3, "Modifying Components."
Figure 11-2 Portal Browser Task Flow Component Properties
The following sections provide information about properties of the Portal Browser task flow and describe the properties on the Parameters tab:
The properties on the Parameters tab of the Component Properties dialog control the default task flow content. For descriptions of the parameters on this tab, see Section 11.3.2, "Portal Browser Task Flow Parameters." For some task flows, parameters on this tab facilitate the wiring of the task flow to page parameters and page definition variables. For more information, see Chapter 19, "Wiring Pages, Task Flows, Portlets, and ADF Components."
Changes to the properties on the Display Options, Style, and Content Style tabs affect the appearance and behavior of the task flow for all users. These properties are common to all task flows. For more information, see Section 14.3.4, "Working with Component Display Options" and Section 14.3.6, "Working with Style and Content Style Properties."
The contents of the Events tab depend on the events supported by the task flow. For more information, see Section 14.3.7, "Working with Component Contextual Events."
All properties on the Parameters and Display Options tabs 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.
Wherever you enter EL on the generic Display Options tab in the Component Properties dialog, the entry is automatically validated. If the EL syntax is invalid, an error appears and the value is neither applied nor saved. Generic Display Options are those cataloged in Table 14-1, "Display Options Properties".
EL validation is not performed on non-generic display options.
If you need EL assistance, an application developer can provide an EL expression; see the "Expression Language Expressions" appendix in Oracle Fusion Middleware Developing Portals with Oracle WebCenter Portal and Oracle JDeveloper.
Table 11-1 describes the parameters that are unique to the Portal Browser task flow.
