Yes, thank you. The collection component works fine!
Now there s another challenge: the length of the timelines containing the collection (of resources).
When I edit the collection, by for example adding more resources, the superior timelines have to be adapted in their duration? Otherwise not all resources will be played or some spots will be repeated until the duration time is over.
Or is there something like an auto-stop-component which leads to the next timeline when the collection component has been played?
