Current Routing Order Problems

Hi, I used the SDK for Java (Version 6.0.0) and i tried to use the function for Routing Order, but doesn´t works. 

My Code 

IntStream.range(0, userSigners.size()).forEach(i -> {

Signer signer = new Signer();

signer.setEmail(userSigners.get(i).getEmail());

signer.setName(userSigners.get(i).getName());

signer.recipientId(String.valueOf(i+1));

signer.setRoutingOrder(String.valueOf(i));

signer.setTabs(tabs);

signers.add(signer);

});

Recipients recipients = new Recipients();

recipients.setSigners(signers);

recipients.setCurrentRoutingOrder("true");

envelope.setRecipients(recipients);

This is correct?
