It all depends on what you mean by "... try to add a second store
with the same call ...". That's a pretty big question. Actual code,
please? :-)

Hi,
does anybody know if it is possible to use two separate in memory
stores with one persistent store coordinator?
I use the following code to create an in-memory store:
NSPersistentStoreCoordinator *psc = [moc
persistentStoreCoordinator];
id store = [psc addPersistentStoreWithType:NSInMemoryStoreType
configuration:nil URL:nil options:nil error:nil];
This works fine. But if I try to add a second store with the same
call, I get the following exception: "Can't add the same store
twice"
So I thought, the two stores needed separate urls identifying them.
But when I start putting names into the URL like in the following line
id store = [coordinator
addPersistentStoreWithType:NSInMemoryStoreType configuration:nil
URL:[NSURL URLWithString:@"storeA"] options:nil error:nil];
I get the following error: "Can't find table for entity Person in
database at URL storeA"
So how do I create two separate in-memory stores in one PSC?
Cheers
Frank
