An instance of a Task control can create a single task instance. If multiple tasks need to be created, use a factory type of Task control. To learn about factories, see "Using Task Control Factories" in Advanced Topics in Using the Worklist, which is located at the following URL:

A Task control instance can also interact with a task instance that already exists by setting its active task ID. After creating or setting the active task ID, your control instance can get information about that task or update that task in various ways.
You can customize Task controls for different business purposes, by adding new operations or callbacks, or by altering the signatures of existing operations or callbacks.
Note: If the Controls tab is not visible, from the menu bar, click View —> Windows —> Data Palette.
Enter a filename for the Task control in the JCX file field, or click Browse to find the JCX file in your file system.

A new JCX file is created and displayed in the Application tab in WebLogic Workshop. (You can double-click any JCX file to view or edit it in the Design or Source View.) The instance of the control is displayed on the Controls tab of the Data Palette.
For examples of designing interactions between a business process and an instance of a Task control, see Using Task and Task Worker Controls in Business Processes.
Task Instances have data values associated with them, many of which are set when the task is created. You can use the Property Editor on a Task control to set the default values for some of these data values. These values are used whenever that control instance creates a new task. Note that the properties set on a factory type Task control propagate to any Task control instances created from that factory.
