Summary0011755: Design decision: should zero payments be possible? -> allow for zero payments in IOS
DescriptionIn Android CHF 0 works, in iOS CHF 0 is not allowed by GUI. The same is valid for other currencies.
Additional InformationOwn opinion: for testing purposes against (live and production systems), w/o balance, zero payments useful. Also for people to see it works "in principle" (if wallets not yet funded).

I'd say: Definitely yes, especially when we have tokens as well.

OK, assigned to @MarcS as for iOS also to allow this; amt field is grayed out when zero.

Paying with tokens, but without money is already possible. E.g. go to shop.TEST.taler.net, choose a chapter, instead of paying テ0.5 for the chapter buy 1 month of access for テ10 to receive a token, then try to buy another chapter. It will automatically get paid with the token.

For people to see how it works "in principle", we have DEMO.

For testing purposes, I will make zero payments available in dev-mode.

v1.6.15 allows both pay-template and p2p to continue with amount:"0", when dev-mode is on.
Pay-template succeeds, but p2p will result in wallet-core error (amount of zero not supported).
