CAknMarkableListDialog

Simple and yet stupid problem with markablelist: implementation using directly CAknMarkableListDialog works well except the fact that I'm not able to override stuff or handle commands etc ... other than that, I can check items and so on.

Now, I'll inherit my own class from CAknMarkableListDialog, overriding nothing for a starter. Other than NewL which is a must but the implementation of that is just passing everything to constructor and that's all.
And all of the sudden, the options menu stops working. What is the problem?
