I set address, amount, payment ID, mix_count=0
push "Send" and nothing...
Actually, it should work except in very few cases (it doesn't show any message after clicking the Send button, but clears the list of recipients). One of those is the daemon being busy (for example, while saving the blockchain). With the wallet RPC that is going to be used in the future (but it isn't good enough to use yet), I will be able to detect failed transfers. In the current version (v0.23.0), the transaction history is not shown due to a bug which is going to be fixed with several other issues discovered during a massive code inspection.
Please use v0.22.0 if the lack of TX history annoys you. I am working hard to resolve all the issues as soon as possible, and will continue to implement features too.
If I do transfer from command line without your client (just from Resources folder) - all is good, and then I can see that transaction in 0.24.0
Thank you for your work!
Not showing a message after sending a transaction is not a bug. It works just flawlessly then (see your transaction history ). Those kind of notifications are still yet to be implemented, but currently, I'm working on an improvement for process handling.
