When the Documents extension is enabled, and is visible as a column in a table view, it’s possible to link any type of view to the entity (not just documents). The same seems to be true for the Whiteboard extension. Is this intended behaviour?
No, this is definitely not. Hotfix this coming soon
Extensions provide a one-to-many relationship between entity and document/whiteboard, which means that a document can only be associated with a single entity. Is this going to remain true, or will it become many-to-many eventually?
Yes, we want to keep one-to-many relationship so that left menu will always be in sync with what you see on entity page
When I associate a document with an entity, the document disappears from the sidebar (I guess to be expected, now that it is ‘owned’ by the entity). However, unlinking the document does not make it re-appear, so it seems to become invisible.
We should not allow to unlink a doc from an entity so far - only to link from another entity. Fix for this is coming
