Update the BPMN file

A UserTask in a bpmn file in its simplest form looks as follows:

<userTask id="simple.initiated" name="INITIATED" activiti:candidateGroups="${approvers}" activiti:candidateUsers="${serviceUser}">
  ...
</userTask>

Here we specify:

the ID of the task
the name of the task
the user roles (candidate groups) who may execute the task, which is managed by Activiti
the users (candidate users) who may execute the task

To add a custom workflow action, add the following to your UserTask:

<userTask id="simple.initiated" name="INITIATED" activiti:candidateGroups="${approvers}" activiti:candidateUsers="${serviceUser}">
  <documentation>Initial state of tasks</documentation>
  <extensionElements>
    <activiti:formProperty id="workflowTaskActionBeans" type="enum">
      <activiti:value id="aBeanNameToMatch" name="an action name"/>
      <activiti:value id="approveWorkflowAction" name="approve"/>
      <activiti:value id="rejectWorkflowAction" name="reject"/>
      <activiti:value id="rollbackWorkflowAction" name="rollback"/>
      <activiti:value id="requestAdjustmentDeletionWorkflowAction" name="request adjustment deletion"/>
      <activiti:value id="requestAdjustmentWorkflowAction" name="request adjustment"/>
    </activiti:formProperty>
  </extensionElements>
</userTask>

where

the formProperty id = workflowTaskActionBeans tells Atoti Sign-Off that it should pick up the contents of this formProperty to resolve one or more Spring Beans.

The id must be workflowTaskActionBeans, otherwise Atoti Sign-Off will not resolve the tasks.This is defined in com.activeviam.signoff.workflow.service.ActivitiService#WORKFLOW_TASK_ACTION_BEANS.

the value’s name specifies the name of the Spring Bean Atoti Sign-Off should resolve.

Take care when selecting the name of the Spring Bean. These must be unique for each action and every other Spring Bean in the application. A good naming convention is to prefix/suffix the bean with something unique to the type of bean, for example, ButtonWorkflowAction. Should you need to overwrite an existing bean you may use @Primary.

Now Atoti Sign-Off can find the actions linked to each task. The next step is to define the actions as Spring Beans.
