Event Contribution Created When No Payment Option Provided

Hi folks,

I didn't have luck trying to reproduce on demo sites (https://demo.circle-interactive.co.uk/ gave me access denied and dmaster was in Russian and taking forever to switch back to English).

The issue:

A client created an event and configured both fees (via price set) and enabled online registration, but forgot to select a payment option (neither payment processor no pending pay later was enabled). This resulted in completed registrations AND completed contributions for the price set options selected.

Desired improvement:

Upon clicking either live or test registration links and/or upon clicking "Save" or "Save and Done", present users with a warning message along the lines of:

"You have listed fees or selected a price set, but no payment option has been selected. Please select at least one payment option or remove fees from the event configuration for an unpaid event".

Any attempt to register for an event configured with fees but without a payment option should result in an error and no registration/event contribution should be created.

Thanks in advance for your time,
Tamar
