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.

Thanks Thomas,

One more question i would like to ask you.
I i need to insert one more object called WorkflowMail and call
WorkflowMail when the above rule condition is True how i can do it.
I can insert the object but how i can call that object in rules.

consistent so you do a null check and then set that same property to an
appropriate value.
