Step 1 - How user can assign task to other
The idea of this exercise is one user assign a task to other.
To do it you should:
- Create two forms in one user will set the user who will execute the next task.
- First task will be assigned to user okmAdmin.
- Create a class which implements AssignmentHandler and assign to taks2.

Example of forms.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE workflow-forms PUBLIC "-//OpenKM//DTD Workflow Forms 2.1//EN"
"http://www.openkm.com/dtd/workflow-forms-2.1.dtd">
<workflow-forms>
<workflow-form task="task">
<input label="username" name="username" />
<button name="submit" label="Submit" />
</workflow-form>
<workflow-form task="task2">
<button name="submit" label="Submit" />
</workflow-form>
</workflow-forms>
Example of ActorAssignment.java:
package com.openkm.workflow.exercise.exercise6;
import org.jbpm.graph.exe.ExecutionContext;
import org.jbpm.taskmgmt.def.AssignmentHandler;
import org.jbpm.taskmgmt.exe.Assignable;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.openkm.bean.form.Input;
public class ActorAssigment implements AssignmentHandler {
private static final long serialVersionUID = 1L;
private static Logger log = LoggerFactory.getLogger(ActorAssigment.class);
@Override
public void assign(Assignable assignable, ExecutionContext executionContext) throws Exception {
log.info("Evaluating assigment");
Input username = (Input) executionContext.getContextInstance().getVariable("username");
if (username != null) {
log.info("Task assigned to '{}'", username.getValue());
assignable.setActorId(username.getValue());
} else {
log.info("Task assigned to 'okmAdmin'");
assignable.setActorId("okmAdmin");
}
}
}
