pbc client doesn't work with indexes

[graphex]

Whenever I try to assign an index to a RObject, it fails on store if I specify an index when the protocol is 'pbc'

        it "pbc client should work" do
            #the test works with :protocol => 'http'
            riak_client = Riak::Client.new(:protocol => 'pbc', :host => '127.0.0.1', :pb_port => 8081, :http_port => 8091)
            testval = SecureRandom.hex(64)
            riak_bucket = riak_client.bucket("test")
            riak_object = riak_bucket.get_or_new("test_key")
            puts riak_object.inspect
            riak_object.data = {:value => testval}

            #the test works without this line:
            riak_object.indexes = {"test_bin" => ["myindex"]}

            riak_object.store
            riak_object.reload
            puts riak_object.data
            newval = riak_object.data["value"]
            newval.should == testval
        end

error is

My storage backend is eLevelDB and the HTTP client protocol works flawlessly.

@graphex This is because you are overriding the entire indexes. The RObject comes prepopulated with its own Hash for indexes whose default value for new keys is a Set. Instead of replacing the whole thing, just append the values you want to the specified index like so:

riak_object.indexes['test_bin'] << 'myindex'

That said, I will see what I can do about making the index structure immune to blind overwrites.
