SimpleRequestProcessor call find twice

Hi,

I have an example class

public class Employee {

public static Employee findEmployee(ObjectId id) {
.................
System.out.println("find");
return employee;
}
......
}

When triggering the findEmloyee from the client side via
RequestContext, the line 'System.out.println("find");' was called
twice, I check that it is called from the class
SimpleRequestProcessor, from the two method

method createReturnOperations, triggered by the line
} else if (!service.isLive(domainObject)) {
in the method

method processInvocationMessages, triggered by the line
domainReturnValue = service.invoke(domainMethod,
args.toArray());

Both this method is triggered from the method
void process(RequestMessage req, ResponseMessage resp)

The questions is why createReturnOpration need to find the employee
again which i think is unnecessary.

It is just loaded from the database and then it will hit the database
again for the same query? Am I doing something wrong here ?

Kind Regards
Andy
