[ns] problem with target_ (Scheduler: attempt to schedule an event with a NULL handler. Don't DO that.)

[Janine Kniess]

 Hi, I'm trying to send a Hello message (I used the AODV protocol model)
and I received the folowing error:

Scheduler: attempt to schedule an event with a NULL handler.  Don't DO that.

The problem is that the 'target_' always returned 0.

Somebody know the solution for this problem?
