How to secify a member function as EVENT-PROCEDURE for async

Hallo,

I have a simple class and inside one member function I have an asynchonous request like this:

  RUN Tests/AddTwoValues.p
        ASYNCHRONOUS SET hProcess EVENT-PROCEDURE "OnAddTwoValuesExecuted"  IN THIS-PROCEDURE              
        ON SERVER hAppServer(INPUT fv, INPUT sv, OUTPUT sumfsv).

Instead of a procedure I have specified a member function named "OnAddTwoValuesExecuted" as EVENT-PROCEDURE.

After executing the method when waiting for the finish of all calls I got an error that procedure of class name has no entry point for "OnAddTwoValuesExecuted".

I have already tried it with a class method too and naming event-procedure "Classname:OnAddTwoValuesExecuted" but all without success.

Has anyone an idea how to do?
