[jbpm-issues] [JBoss JIRA] Deleted: (JBPM-1208) problems with activity instances

problems with activity instances -------------------------------- Key: JBPM-1208 URL: https://jira.jboss.org/jira/browse/JBPM-1208 Project: JBoss jBPM Issue Type: Bug Reporter: Tom Baeyens Guillaume reported: I tried to use a pvm with activityInstances in Orchestra and I had some problems in ExecutionImpl: - method createActivityInstanceScope: hasActivityInstances is set to true only if activityInstances == null. But with hibernate, when a collection is fetched from the database, it is never null, but it is an empty collection. As a result, hasActivityInstances is never set to true. - method destroyActivityInstanceScope: if the list of activityInstances is empty, it is set to null. This creates an exception with hibernate. - method destroyActivityInstanceScope: this methods modifies the node field of the execution, this breaks the value of previousNode. (previous node is used in bpel sequences) Why is the execution node updated when an ActivityInstance is destroyed ? regards, Guillaume
