Filtering on 2.6.2 is not working.
Mike,

I guess the filtering is broken in this new version (2.6.2). Setting my adapter to mAdapter.filter("") doesn't bring my list back. I've managed to revert the filtering if the library version was 2.5.1.

You can see my code here in this gist : https://gist.github.com/jelther/9c0bf03c34a47110c6484cfc2750ed5e

There are some comments because it looks you've changed the way to access the filtering methods.
