Workflow::NoTransitionAllowed error, but event is defined for the state

[HashtagONUD]

Discovered that if I comment out the if symbol, the workflow works as normal:

    state :tsp_isnow_0_state do
      event :tsp_wasasked_1_event, transitions_to: :tsp_wasasked_1_state # , if: :both_locations_exist?
    end

It also works when I keep the if condition, but return true from theboth_locations_exist? method. If the method returns false, I get the same error as before.

To allow/prevent transition during the runtime depending on some condition, please read the documentation for "Conditional event transition" https://github.com/geekq/workflow#conditional-event-transitions
You need an :if parameter (will call the function to decide to allow or prevent the transition) and not the if modifier you use, when defining the workflow (this just prevents the event definition from the beginning).
