At a glance, it looks to me like the merge callback should always get 
called (this is the responsibility of your protocol).  If merge is 
called, layer.destroyFeatures gets called (yes, this is a blunt merge).

So, I'm guessing something is going wrong in the protocol.  Could be a 
parsing error.  If you are seeing any errors or have any more detail, 
please open a ticket and attach anything relevant that helps reproduce 
the problem (relevant detail would include at least the format and 
protocol that you are using and ideally an example).

Thanks,
Tim
