Tasks

Once you have created your custom tool, it will need to perform an action when the user clicks the button or selects the menu item. You may write code to execute any type of action you want.

This section discusses one possible option: tasks. The default tools provided with Workflow Manager call tasks to execute actions. Tasks consist of subtasks. You may also create custom subtasks.

Interfaces:
    IMMPxTask
    IMMEnumPxTasks
    IMMPxNode3

Tasks are created using the Process Framework Admin Tool (see Process Framework Admin Tool online help). This section describes the code used by the Process Framework Admin Tool to create the task as it is designed by the user.

Enable a Task

If you have created a task and it isn’t enabled in your extension, there may be several reasons. The Enabled method on the IMMPxTask interface does several things before enabling a task.

If a transition has been assigned to the task, it checks to ensure the transition enabled. It also looks to see that the transition’s state change is valid and can be performed on the selected node, and that the user has a role with permissions to perform the state change on the selected node.
If no transition has been assigned to the task, then the Enabled method looks at the roles of the task to ensure the user has a role that matches one of the task’s roles.
Next, the Enabled method creates and calls enabled on each subtask. If any subtasks returns an enabled value of false (or disabled), the entire task is disabled.
