In-Depth Information
This interface allows us to see the different process definitions available to start them, but
we still need an interface to see the currently running process instances and its internal
state. For that, there is another option in the
Process Management
navigation bar option,
called
Process Instances
. In the following screenshot, we can see the task initiated by
completing the form in the preceding screenshot:
The UI allows us to filter process instances by their state, see their details, send signals to
them, or abort them. But this is mostly an administrative topic to handle process systems.
End users would mostly interact with the tasks assigned to them, or their roles. To do so,
the workbench needs a way to show:
• A collection of all the different human tasks with which a user can interact
• A particular form to interact with each one of the said human tasks
For that purpose, the workbench provides us with task lists and task form interfaces.
Task lists
It is important that all asynchronous tasks (that the process runtime is waiting to be com-
pleted) have a way to be managed from external tools. The case of human tasks is special,
because they won't be handled by an automatic external system, but by people who need a
UI to interact with said tasks. For that purpose, the workbench provides a way to see tasks
that are either owned by the current user or could be assigned to the current user in the
form of lists. On this view, we can perform a series of different actions on each task: claim
