CoreData : fundamental (or not) questions

Hi,

Please if someone could answer to the following "theoritical" questions...

1- In which cases is it necessary to create another managedObjectContext, instead of using the default moc of the NSPersistentDocument ? Of course if you have different persistent stores it seems to be necessary, but in the simple case : 1 managedObjectModel, 1 persistentStore ?

2- How can I access the default moc of the document from an entity (I mean by entity, a class created from an entity) ? Is this the good way : [[[NSDocumentController sharedDocumentController] currentDocument] managedObjectContext]]; ?

3- How can I access the methods of an arrayController from an entity ? I mean the arraycontroller of the entity itself or the arraycontroller of another entity. I think I can't add outlet to entity.h since this file can not be imported in IB. So outlets and actions should only be in MyDocument ?

Thx in advance.
