While a debugger session is active, we can open the object being debugged in an appropriate Designer, change the object, save, and recompile it. The revised object will immediately be available to other sessions on the system. However, the version of the object that is being executed and in view in the debugger is the old version of the object, not the changed one. Furthermore, if we refresh the view of the code in the Debugger Code window, the new version will be displayed while the old version continues to be executed, leaving potential for significant confusion. Therefore, it's best not to change an object and continue to debug it without starting a new session.
