In Pre-Exit, prevent method from being called

Question

I have created an enhancment for a webdynpro component. Then, I have defined a pre-exit for a method in the component controller. Inside the pre-exit, I do a couple of checks, and depending on them, I would like to skip the processing of the method for which I have define the pre-exit. Is this possible?
I thought of the RETURN statement, but this won't help. RETURN will jump out of the pre-exit, but not out of the method.
my-pre-exit-of-method-SET_MY_VALUE.
  IF some_condition = some_value.
    "prevent the method SET_MY_VALUE from being called. but how??
  ENDIF.
end-of-pre-exit.

Answer 1

I just find out how to circumvent this...
The trick is to use "Overwrite exit".  Add your own codes.  Depending on your conditions, you can call back the original method.  But when you call the original method, you need to use the syntax:
me->original_method(...)
Do not use:
wd_this->original_method(...)
Using "me" will only call the original method; using "wd_this" will trigger your overwrite exit which means this will jump to a recursive call to your own exit; This will certainly drain the resources of your system indefinitely until it dumps.
