The WorkflowTaskQuery component in the registration workflow is a servlet bean of class atg.workflow.servlet.WorkflowTaskQueryDroplet. You can use this servlet bean to perform workflow task queries; for example, you could create a UI that displays the ID of the workflow subject and the names of all tasks (including completed and inactive tasks), with links from each task to a page where the task can be viewed in more detail, and where operations can be performed on the task. The task’s identifying information (its process name, segment name, subject ID, and task element ID) can be extracted from the TaskInfo and passed to this page as parameters. These parameters can then be used as inputs to the WorkflowTaskFormHandler, which can display task information and perform operations on the task, including firing task outcomes. See the Workflow Task Form Handler section for more on WorkflowTaskFormHandler.
