how to add custom objects to the process instance?

how to add custom objects to the process instance?

this work:

variableMap.put("assignee", authorizatorObject.getAuthorizator());

this won't
variableMap.put("authorizatorObject", authorizatorObject);

because activiti doesn't know my object!?!?

or on the process definition i need to declare authorizatorObject variable?

want to have the authorizatorObject on my process model

1. The object need to be Serializable!!!
   

2. /get pedidoAutorizacao object from the process
              pedidoAutorizacao = (PedidoAutorizacao) getActivitiEngine().getRuntimeService().getVariable(task.getProcessInstanceId(), "authRequest");
