Class ChangeProcessInstanceVersionCommand

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

All Implemented Interfaces:

java.io.Serializable, Command

public class ChangeProcessInstanceVersionCommand
extends AbstractProcessInstanceBaseCommand

THIS COMMAND IS NOT YET STABLE, BUT FEEL FREE TO TEST :-)
Status update: Still not complete, but refactored and added simple test cases: ChangeProcessInstanceVersionCommandTest.
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 or a name mapping has to be provided.
Currently known limitations:

• Tasks cannot move "into" another node. If an active TaskInstance exists, the Task definition must exist in the TaskNode with the same (or mapped) name. Otherwise the right node cannot be found easily because it may be ambiguous.
• Sub processes aren't yet tested. Since the ProcessState is a Node like any other, it should work anyway.
• Can have negative impact on referential integrity! Because one ProcessInstance can have ProcessLogs point to old ProcessDefinitions. Hence, delete a ProcessDefinition may not work and throw an Exception (Integrity constraint violation)
• In combination with ESB the ESB uses Token.id and Node.id as correlation identifier. After changing the version of a ProcessInstance the Node.id has changed, so a signal from ESB will result in an exception and has to be corrected manually.
