How to pass all parent variables to a called process

ound an answer, thought I'd post  for  others to use. In the called process, define a start event listener that looks up the  super  execution and pulls all the variables local. Very handy and easy.
public  class  WorkflowVariableInjectorListener  implements  ExecutionListener {
  private  static  final  long  serialVersionUID = 1L;

  static  Logger logger = Logger.getLogger(WorkflowVariableInjectorListener. class );

  @Override
  public  void  notify(DelegateExecution execution)  throws  Exception {
    logger.info( "In notify" );
    if  (execution  instanceof  ExecutionEntity) {
      ExecutionEntity executionEntity = (ExecutionEntity) execution;
      ExecutionEntity parentEntity = executionEntity.getSuperExecution();
      if  (parentEntity !=  null ) {
        // Copy all the variables into me
        executionEntity.setVariables(parentEntity.getVariables());
      }
    }

  }
