Class ChangeProcessInstanceVersionCommand

java.lang.Object
  org.jbpm.command.ChangeProcessInstanceVersionCommand

All Implemented Interfaces:

java.io.Serializable, Command

public class ChangeProcessInstanceVersionCommand
extends java.lang.Object
implements Command

THIS COMMAND IS NOT YET STABLE, BUT FEEL FREE TO TEST :-) change the version of a running process instance. This works only, if the current node is also available in the new version of the process definition (identified by name, so the name has to be exactly the same). One problem with this approach ist also, that if a task with the same name is moved to another node (but this is a rare case) make trouble, if there are 2 tokens in the process, because only one actual node is used... Possible workaround: use process id instead of node id. TODO: new hibernate query for that: [16:23] Fluffi: "select distinct task " + "from " + Task.class.getName() + " task " + "where task.name = :taskName " + " and task.processDefinition.id = :processDefinitionId ";
