If you already have it in your working memory then just add an additional condition in your rule with no constraints:
rule "Your First Rule"
when
m: Workflow(workflowActorId==null,myid:workflowActorId)
email : WorkflowMail()
then
System.out.println(myid + "its null values");
m.setWorkflowId(0);
email.doSomething();
update(m);
update(email); // if you have conditions on email and want rule re-evaluation to happen
end
Alternatively you could have WorkflowMail as a global if you only have one instance of it, or add appropriate constraints if there are multiple instances - otherwise your rule will fire multiple times, once for each one of them.
