Use of task node
From OpenKM Documentation
Now we are going to see how you can create task in jBPM and assign them to actors who will perfom the task. Actors also can select a pending task and assign to himself.
First of let's create a process definition called "task" with an initial node, a task node and a end node:
As seen previously, a task node represents one or many tasks executed by a human person. When the process execution arrives to a task node, an task instance is created in the workflow member list. This node will enter in a wait state until the user notify the conclusion of the task.
In order to create a task in a task node, go to the properties of this node.
