4.1.4.2 User Tasks

The most common kind of task is the user task, which is executed by participants of the workflow.

When defining a user task, first consider the rule that selects which users to offer the task. Usually, the appropriate users are selected from their groups. For each group, a list of rights on the task is given, where accept is the most important one for user tasks. For special requirements, you can implement your own business logic in a WfPerformersPolicy.

For a user task a client view has to be given. A client defines a view on the variables of the workflow that may be read and/or modified. For resource variables, you can additionally determine whether the referred content may be editable.

Validators (see Section 4.1.7.4, “Validators”) have a special feature in the context of a client view. If a validator fails and provides a description, it is displayed as an error message in a client view. Like task descriptions, validator error messages may be localized (see Section 4.1.4.1, “Common Features of All Tasks”).
