The attribute autoComplete controls the completion of a stage instance. The following table describes the completion criteria of a stage instance based on the autoComplete property.

• autoComplete = true: There are no children in the ACTIVE state, and all required (see Required Rule) children are COMPLETED, DISABLED or TERMINATED.
• autoComplete = false: There are no children in the ACTIVE state, and
  • all children are COMPLETED, DISABLED or TERMINATED, or
  • on manual completion using CaseService#completeCaseExecution, all required (see Required Rule) children are COMPLETED, DISABLED or TERMINATED.
    For a CasePlanModel the property autoComplete can be set as follows:

<case id="case">
  <casePlanModel id="CasePlanModel_1" autoComplete="true">
    ...
  </casePlanModel>
</case>

For a Stage, the following XML can be used:

<case id="case">
  <casePlanModel id="CasePlanModel_1" autoComplete="true">
    <planItem id="PI_Stage_1" definitionRef="Stage_1" />
    <stage id="Stage_1" autoComplete="true"/>
  </casePlanModel>
</case>
