I've been searching and cannot find a way to achieve this: display content referencing a content that is referenced by the content being displayed.
It may be somewhat confusing but I'll do my best to be clear:
I have two content types: 'Company' and 'Service' As you can imagine a Company provides many Services, so there is an Entity Reference field in Services that points to the Company providing it.
That's it: Service content points to Company content in a many to one relation, many services point to one company (the company that provides them)
When I display a Service, I also display the company that provides it through the Entity Reference field.
Now the tricky part is: When displaying the page for a Service, I'd like to also show (e.g. in a sidebar) the other services provided by the Company that the displayed Service is pointing to.
I'm using Panels and Views on Drupal 7.
Please note: this is not a simple 'related content block', that's what I am using to display the company providing the content or when displaying the Company content
