Contrary to what happens in eZ Publish 4.4, In eZ Publish 4.2 it is possible to remove a main location node of an object, even if the node has multiple locations.

In 4.2, when the main location is removed, another main location is selected among the existing secondary locations. It could be useful to allow users to remove an object from all it's locations upon removing from the main one.

Steps to reproduce

Create an object.
Add a secondary location to the object
Remove the main location

• The object's main location will shift to the previous secondary location.
