try {

• actions <- execute / throws errors
• ChangeArrayActions[action] <- send
• this.eventEmitter.emit(events.changeArrayReadyToWrite)

} catch {

• save changeArray / so that the dataChanges can be invoked later based on the saved file }

reason:

1. actions can throw error and that should stop emition of changeArrayReadyToWrite
2. the expected actions should be stored on error, so that they can be reloaded
3. the error should state exactly which action and with what parameters went wrong, so this can be reinvoked easily
