Overriding function does not execute EV<< command?

Question

I'm using Omnet++ 4.6 and I created a class to inherit AODVRouting. Now, I created a function in my new class that overrides handleMessage() from the parent class. Compiler indicates that the function is indeed overridden. I typed an EV<< command to print the start of the function to event log, yet it does not print to the event log. What is the problem??

Function in the the parent class is virtual and protected. This is my inherited class.cc:

*/

            //we can add a delay before sending the copy of the message again (10 time units)
        scheduleAt(simTime() + 1, ReplayMsg);
        //sendDelayed(ReplayMsg, 0.1,"ipOut");
        ReplayedMsgs++;
        std::cout<<"Launched Replay Packet!\n";
        EV<<"Launched Replay Packet!\n";
        this->bubble("Attack");

In order to view own messages generated by EV you need to switch log viewer to "module output" mode. Start the simulation, and in the bottom right window press the rightmost icon.

I did that, it's not what I meant. For some reason I'm tending to think that my overriding function is not invoked... Only the parent class function is invoked :( – Shaikha TheGreen Oct 18 '15 at 14:48

Make sure Class is registered has the macro >> Define_Module(....); (seems done)
Make sure Class is linked >> you should be able to get a full list of all registered classes in your simulation by running it with the "-h classes" option
Verify that the name in the ned file is the same as the configuration file cc
try this right click on the folder of the project Properties >> Omnet++ >> Makemake >> Apply
