Hello Core-Team,

I'm just trying to get my URLs for events2 working again. Here is my configuration:

routeEnhancers:
  Events2ShowPlugin:
    type: Extbase
    extension: Events2
    plugin: Events
    routes:
      -
        routePath: '/show/{date}/{time}/{event_title}'
        _controller: 'Day::show'
        _arguments:
          date: timestamp
          time: timestamp
          event_title: event
    requirements:
      date: '\d+'
      event_title: '^[a-zA-Z0-9]+\-[0-9]+$'
    defaultController: 'Day::show'
    aspects:
      date:
        type: TimestampMapper
        format: 'Y-m-d'
      time:
        type: TimestampMapper
        format: 'Hi'
      event_title:
        type: PersistedPatternMapper
        tableName: 'tx_events2_domain_model_event'
        routeFieldPattern: '^(?P<title>.+)-(?P<uid>\d+)$'
        routeFieldResult: '{title}-{uid}'

I get the error message:
Route pattern "/extensions/events2/show/{tx_events2_events__timestamp}/{tx_events2_events__timestamp}/{tx_events2_events__event}" cannot reference variable name "tx_events2_events__timestamp" more than once.

That does not make sense as I have given them the name <date> and <time>. Is there a possibility to use my namings for these variables? Or you can number these Variables like in Doctrine :

/extensions/events2/show/{tx_events2_events__timestamp-0}/{tx_events2_events__timestamp-1}/{tx_events2_events__event-2}
