I have the following setup: a content type (event) can have a "mother" event, which is configured as entity reference (Basically it's the same event on another date).
I have a view for a single event which is embedded in a panel pane and another view for the other similar events (with the same "mother") in another panel pane on that page.
This works pretty good, except when i try to filter out the event that is shown on the first pane from the second pane, so that this one isn't shown twice.
The view for the "related events" has a contextual filter of the nid and relationship to the "motherevent" which is set to "required".
Now you would say, check the exclude field for the contextual-filter. Yes, this works, but with a side effect: all other events not related to the "mother" are shown as well.
I feel like I have arbitrary tried all possible combinations of "set relationship" / required and so on, but with no effort. I even tried a second contextual filter of the nid with different settings... I don't get it.
Can someone please explain how this could be achieved? Thanks a lot!
