I'm playing with BIP70 payment requests, but I can't get them to sign properly. The Bitcoin Core client (v0.11.0) only ever shows the bitcoin address, never details from the certificate.
I thought I must be doing something wrong, then I tried with Gavin's Handy-Dandy payment request generator at
https://bitcoincore.org/~gavin/createpaymentrequest.php but I can't get a payment request that shows anything other than the receiving address in the Bitcoin Core client from there either.
Is there something wrong with the requests, or is Bitcoin Core not showing them properly, or am I just being dumb?
