Example 1 with MultiInstanceActivityBehavior

use of org.camunda.bpm.engine.impl.bpmn.behavior.MultiInstanceActivityBehavior in project camunda-bpm-platform by camunda.

the class LegacyBehavior method removeLegacySubscriptionOnParent.

/**
 * <p>Required for migrating active sequential MI receive tasks. These activities were formerly not scope,
 * but are now. This has the following implications:
 *
 * <p>Before migration:
 * <ul><li> the event subscription is attached to the miBody scope execution</ul>
 *
 * <p>After migration:
 * <ul><li> a new subscription is created for every instance
 * <li> the new subscription is attached to a dedicated scope execution as a child of the miBody scope
 *   execution</ul>
 *
 * <p>Thus, this method removes the subscription on the miBody scope
