Account change address is not showing up with `getaddressesbyaccount`

Question

I have a tiny question regarding the Bitcoin JSON-RPC API. I have a transaction on Testnet which sends one coin to an other address owned by me (on an other account than the sender). The sending address, mtGaEd9zZU8B7aYSuQiDFZTo2wiS8dWb3c, is listed under the default account, running getaccount mtGaEd9zZU8B7aYSuQiDFZTo2wiS8dWb3c outputs indeed an empty string. The receiving address, mzcj8xYome3gmAWZG57yutv14sctPxbPV6, is listed under an account named test, as expected running getaccount mzcj8xYome3gmAWZG57yutv14sctPxbPV6 returns test. Both addresses also show up when I use getaddressesbyaccount, but the change that went to address mnUJRd9CL3GV1QbWFxJxLj2DgE1ADSB8oR, which also returns an emtpy string when using it as argument to getaccount, doesn't show up in the getaddressesbyaccount call output. Why is that? I can't sum the balances of each addresses now for a reliable account balance, only getbalance return the right answer.

Answer 1

Call listreceivedbyaddress(0, true) to get all of your addresses (even the empty ones or those who have a zero-confirmations balance).

By default (parameterless) it will only list the addresses that contain some confirmed balance and those who have at least one confirmation for their unconfirmed balance.

Answer 2

It doesn't show up in the results from getaddressesbyaccount() because addresses are only associated with accounts by use of getnewaddress() or setaccount().
