Ruote::Exp::ErrorExpression

Triggers an error directly from the process definition.

Ruote.process_definition :name => 'log1' do
  sequence do
    perform_inventory
    error 'inventory issue', :if => '${f:level} < 1'
    order_new_stuff
    store_new_stuff
  end
end

Replaying the error will 'unlock' the process.
