It's not possible to produce and subscribe to events using Otto?

Question

I'm trying to Subscribe and Post from the same fragment, but I'm getting this error when i try to register the fragment:

...(my method) has @Produce annotation but requires 1 arguments.  Methods must require zero arguments.

on

 BusProvider.getInstance().register(this);

So i guess it's not possible, but maybe there is an alternative without additional interfaces.

Thanks in advance!

Methods annotated with @Produce must not take any arguments. They should just return the event object.

"I'm trying to Subscribe and Post" suggests you probably need to change it to @Subscribe annotation instead.

For posting events, just use post(). @Produce is meant for returning the latest value of an event.

I need to post 1 object and receive 1 object from another place. I need both operations for different objects. – Motheus Oct 08 '14 at 07:00
Use `post()` for posting then. – laalto Oct 08 '14 at 07:00

oh thanks!. I thought that it was necessary to write the @Produce + method thing all the time. – Motheus Oct 08 '14 at 07:03
