I am trying to create a dynamic event subscription, for drupal8 commerce order state. My use case is the following. I want to create an invoice for any order which goes into stage e.g. PENDING. There is a custom stage/transition yml which i have created. The PENDING state is to be configured in a custom settings form, for my custom module. Therefore the user should be able to add one or more states in a field, and the invoice creation should only be done when an order enters one of these states. In terms of code, in the event subscriber, i have the following code public static function getSubscribedEvents() { $events = ['commerce_order.place.post_transition' =>'onTriggerInvoiceCreation']; return $events; } public function onTriggerInvoiceCreation(WorkflowTransitionEvent $event) { $invoice_creation_states = explode(",", $this->config_factory->get("my_custom_module.settings")->get("invoice_creation_states")); $current_state = $event->getToState()->getId(); if(in_array($current_state, $invoice_creation_states)) { //create the invoice } } So, a far as i understand, i need to do one of the following In function getSubscribedEvents, i read the my_module.settings from configuration and find a way to construct the correct event subscriber. As this function is static, i dont seem to be able to use config factory service. So next thought is to create a more generic event listener, for all order state changes, and get configuration settings and make the appropriate condition in the corresponding event listener function. Question: Is there a more generic transition event than commerce_order.TRANSITION_ID.TRANSITION_PHASE something like commerce_order.ANY_TRANSITION.ANY_PHASE ?
