The Worklist service provides access to all the worklist items that require your attention. These worklist items are displayed on your application page, where you can view and act on all items in one place. These worklist items may be queried from all of the BPEL servers configured in your application.
This chapter contains the following sections:
This chapter is intended for users interested in understanding and using the features of the Worklist service to track their tasks, notifications, and alerts.
The Spaces application administrator has the authority to expose or hide task flows from a particular service. Tasks discussed in this chapter are not available to you if the relevant service is hidden.
For information about seeded user roles, see "Managing Users and Roles for WebCenter Portal: Spaces" in Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter Portal.
The Worklist service provides access to BPEL worklist items that are created when a BPEL workflow process is invoked, or when messages are sent to the worklist channel on the Oracle User Messaging Service.
In Spaces, the Worklist task flow (Figure 70-1) enables you to view and respond to all the worklist items that are allocated to you. If BPEL workflows are enabled in Spaces, you must add a Worklist task flow to a page if you want to see your space membership notifications, invitations to join new spaces, and so on.
The Worklist task flow provides a fast and easy way to view and respond to messages, alerts, and notifications from the automated processes in place in your organization. You can click an item in the Worklist task flow to view details in a separate window (Figure 70-2).
For example, in Spaces, if you are selected as an approver for space membership, every time a user applies to become a member of the space a notification is sent to your Worklist. This is just one example of the types of notifications and requests that can be posted on your Worklist.
One Worklist item might be a request for space membership. Response to such a request would be to approve or reject it. Another Worklist item might be a notice of acceptance as a member of a space. Response to such a notification would be to acknowledge that you have received it. These are two small examples of a much wider range of possible messages, alerts, notifications, and responses.
The Worklist only shows items from the Oracle SOA Suite BPEL Servers. Some Worklist items are kicked off by events that are associated with an externally defined workflow. A workflow maps the route an item follows after an event kicks off. For example, a workflow might define the way a project assignment is routed, such as from administrator, to moderator, and then to participant. Additionally, it specifies what happens (if anything) when the assignee responds (such as with an Acknowledge). This type of workflow is enabled in a Workflow server that comes with Oracle SOA Suite. The definition of these workflows is an administrative or development task.
The Spaces application also has internally-defined workflows. An example of an internally-defined workflow includes the process of subscribing to a space. A user requests a subscription. The request appears on the space moderator's Worklist. If the space has multiple moderators, the first response to the Worklist item is to claim ownership of the request, so that only one moderator responds to the request itself.
Messages, alerts, and notifications might also come from the User Messaging Service. The Worklist task flow includes a control for accessing messaging preferences on this server (Figure 70-3). Clicking the Messaging preferences icon displays the User Messaging Preferences page in which you can specify the channels over which to receive User Messaging Service messages and define messaging filters.
For information about setting messaging preferences for the User Messaging Service through the Spaces application, see Section 70.3.2, "Setting Messaging Preferences."
Every 15 minutes, the Worklist task flow refreshes automatically with new messages, alerts, and notifications. Optionally, you can update your view yourself by clicking the task flow's Refresh Worklist icon (Figure 70-4).
The Worklist task flow does not get refreshed automatically when you perform an action on any task. You must refresh the task flow to list the latest items.
Roll your mouse pointer over the Refresh Worklist icon to display the date and time the task flow was last refreshed.
To assist you in maintaining an organized view of your Worklist items, the Worklist task flow provides a variety of display options, accessible from the Worklist toolbar (Figure 70-5).
Worklist display options enable you to approach responding to messages, alerts, and notifications according to timeliness and relevance.
For more information about Worklist display options, see Section 70.3.3, "Arranging Your Display of Worklist Items."
For the steps to add a Worklist service task flow to a page, see Section 17.5, "Adding Resource Catalog Components to Pages."
You can add worklist task flows in personal pages only.
The Worklist task flow provides a fast and easy way to read and respond to items from the automated processes in place in your organization. All of the information on the Worklist is specifically relevant to you.
This section provides information about the Worklist task flow and describes how to use it. This section includes the following subsections:
To view a task, message, alert, or notification, simply click the Details link (Figure 70-6).
Any Worklist item that is no longer of the
Assigned state is removed from the Worklist during the next refresh.
The Worklist Messaging preferences icon provides access to controls for specifying your messaging preferences on the User Messaging Service. Use messaging preferences to specify the channels over which to receive User Messaging Service messages and to define messaging filters. User Messaging Service messages may include Worklist notifications in addition to other notifications and alerts from other consumers of the server.
Messaging channels are the channels over which messages, notifications, and alerts are received from the User Messaging Service. These include mail, voice over internet (VoIP), and the like. Messages, notifications, and alerts come from the services that are registered with the User Messaging Service.
Messaging filters define sorting conditions for messages and specify the channels through which to send messages that meet those conditions.
You can define messaging channels and filters using the User Messaging Preferences dialog. This section provides an overview of how to use this dialog to configure messaging channels and define messaging filters for messages generated from the User Messaging Service. For more information, see the User Messaging Service online help and the chapter "Oracle User Messaging Service Applications" in Oracle Fusion Middleware Developer's Guide for Oracle SOA Suite.
To access the User Messaging Preferences dialog from the Worklist task flow:
Log in to your application.
Click the Messaging preferences icon in the Worklist toolbar and specify credentials to log in to the BPEL server.
In Spaces, you can access the Worklist service by expanding the Worklist pane.
A web page opens with two tabs (Figure 70-7):
Messaging Channels—Configure channels (such as mail, voice, and so on) to receive your User Messaging Service notifications and alerts.
Messaging Filters—Define rules for filtering your User Messaging Service notifications and alerts.
Configure channels and filters by referring to the User Messaging Service online help.
This section describes how to use Worklist sorting and grouping options to arrange your display of the Worklist. Sorting affects the display order of Worklist items. Grouping divides items into groups that share a common attribute, such as a common category, a shared priority level, or some other common attribute.
You may notice a number next to each group (Figure 70-8). These indicate the number of items contained in a particular group. To expand a group and see the items it contains, click the Expand icon to the left of the group title.
To arrange your display of Worklist items:
Log in to your application.
Click the Display Options icon at the top of the Worklist on your application page.
In Spaces, you can access the Worklist by expanding the Worklist pane.
In the Display Options dialog box, expand the Group By list (Figure 70-9), and select an option for grouping your Worklist items.
Category—Group Worklist items into their assigned categories. Items that do not belong to a category are grouped under the heading Not Categorized. Whether a Worklist item includes a category is determined by the workflow developer; consequently, not all items might include categories.
Create Date—Group Worklist items according to the date they were created, starting with the most recent.
Due Date—Group Worklist items according to when they are due. Due dates are optional; therefore, some items may not have them. In such cases, the date the item was created is used.
Expiration Date—Group Worklist items according to when they are due to expire. Expiration dates are optional; therefore, some items may not have them. In such cases, the date the item was created is used.
Not Grouped—Do not group Worklist items. When you group Worklist items by Not Grouped, the Worklist displays items in a flat list. All other grouping options display the items in a tree format.
Priority—Group Worklist items according to priority, either high, normal, or low. Table 70-1 illustrates the priority indicators that are used in the Worklist.
Worklist Server—Group Worklist items according to the server from which they originated.
Select a Sort By option (Figure 70-10).
Create Date—Sort Worklist items according to the date they were created, starting with the most recent.
Due Date—Sort Worklist items according to when they are due. Due dates are optional; therefore, some items may not have them. In such cases, the date the item was created is used.
Expiration Date—Sort Worklist items from the most recent expiration to the furthest away. Expiration dates are optional; therefore, some items may not have them. In such cases, the date the item was created is used.
Priority—Sort Worklist items from highest to lowest priority (see Table 70-1 for illustrations of priority indicators).
Title—Sort Worklist items first from 0 to 9 then from a to z.
Click Save to save your changes and close the Display Options dialog box.
The Worklist displays newest created 25 items per Worklist server connection. For items exceeding the 25-item limit, follow the link to the BPEL Worklist Application, where you can view and act on a larger volume of Worklist items.
The Worklist service task flows have associated properties, which users with sufficient privileges can access through the Component Properties dialog in Oracle WebCenter Portal's Composer (Figure 70-11). Many properties are common to all task flows, and the method for accessing task flow properties is the same from task flow to task flow. Common task flow properties and how to access them are discussed in Section 17.5.2, "Setting Properties on Page 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 17.5.2, "Setting Properties on Page Components."
The Child Components tab displays all of the components contained within the current component. It provides controls for rearranging, showing, and hiding child components. Not all components contain children. So you may find this tab devoid of content. For more information, see Section 126.96.36.199, "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 188.8.131.52, "Working with Component Contextual Events."
All properties on Display Options tab 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 Expression Builder icon next to a property field to open the editor. For more information about using the editor and for descriptions of common EL expressions, see Appendix B, "Expression Language Expressions."
Wherever you enter EL on the generic Display Options tab in the Component Properties dialog, the entry is automatically validated. If the EL is invalid, an error appears and the value is neither applied nor saved. Generic Display Options are those cataloged in Table 17-1.
EL validation is not performed on non-generic display options.
