It seems that there are two differents Location objects:

• global class Location extends SObject
• global class System.Location

Because System is the default namespace, I can not refer to the SObject Location in APEX.

Example (in Location trigger):

Map<Id, Location> newLocations = (Map<Id, Location>) Trigger.newMap;

--> Incompatible types since an instance of Map<Id,SObject> is never an instance of Map<Id,System.Location>

Is there any way for me to get those SObject ?
