Known issues / Roadmap

  • This modules intended used with backend, so the validation error are enough to show user what is wrong, when website_event is installed public user would try register attendees. As soon try more than one attendee this will trigger validation error as the attendee partner is duplicated the error shown is 500 internal server error which is no appropriated.
  • It would be necessary have a new module with depends on website_event and this one to prevent this issue.
  • Another kind of problem is with event_sale module that would try use Sale Order contact as attendee that will lead to the issue of attendee duplicates if try to buy two times same event.
