A question about the setLink method

Aug 24, 2010 at 5:10 PM

There is a problem with the method setLink:sourceProperty:targetObject: of the ObjectContext class. According to documentation, its sourceProperty parameter is "The name of the property on the source object that represents the source in the link between the source and the target". I added the following call to my code:

[self.dataSource setLink: parentObject sourceProperty: @"Configuration" targetObject: childObject];

but it throws an "Invalid operation" exception telling that "AddLink and DeleteLink methods only work when the sourceProperty is a collection.". Well, the "Configuration" property is a collection:

@property ( nonatomic , retain , getter=getConfiguration , setter=setConfiguration )NSMutableArray *m_Configuration;

By debugging this call, I found the following "if" statement (ObjectContext.m, line 967):

if([[[array objectAtIndex:j] objectForKey:@"Type"] isEqualToString:sourceProperty])
My question is: why property name is compared with its type?

It seems that the problem hasn't been fixed in version 1.1. I updated to this version and I continue receiving the same error. This code:

 

if([[[array objectAtIndex:j] objectForKey:@"Type"] isEqualToString:sourceProperty])

 

is not changed.

I'll check with the dev team. This was supposed to be fixed in the 1.1 release.
