getnewadress or keypollrefill - return error in cold wallet

[inzider]

Hi,

I just can't generate a new address in cold wallet.

Using the cold wallet client, if I enter getnewadress, I get this error:
$ Keypool ran out, please call keypoolrefill first .

Then, trying to run keypoolrefill, or keypoolrefill=1000 or keypool=100, I get this error:
$ Method not available in cold version of MultiChain.

On a fun fact, the keypool= option is available in the cold wallet help menu.

I tried run the keypool command on a unlock cold wallet with walletpassphrase abcxyz, but same result, as trying to run command on hot wallet, where the command seems to work without any flaw but dosen't help on the cold wallet getnewaddress issue.

Anyone know ho to get new address in a cold wallet?

Regards,

Inz
