I figured out my problem. I had put an object representing the document into
the nib where the document was also set as the file's owner, making each
document call init twice.
A hard-learned lesson. At least I won't forget it.

I'm making a document-based application, backed by core data, but I'm having
serious issues opening the documents again.
I'm trying to use readFromFileWrapper(wrapper, ofType:type, error:err) in an
NSDocument subclass.
Through my logging, it seems that this method is doing what it should, but
the document that is displayed is not the object that I query inside that
method, as can be seen by the two calls to puts self in the snippets below.
def readFromFileWrapper(wrapper, ofType:type, error:err)
url =
NSURL.fileURLWithPath(self.fileName).URLByAppendingPathComponent(test.storedata)
setFileType('SQLite')
add_persistent_store(url)
puts crags # This is a method that fetches objects from the sqlite database,
# and proves to me that the database has been set right. Output
below:
# #RFCrag_RFCrag_:0x4013323c0
# #RFCrag_RFCrag_:0x4013324c0
# #RFCrag_RFCrag_:0x401332680
# #RFCrag_RFCrag_:0x401334480
# #RFCrag_RFCrag_:0x401334740
# #RFCrag_RFCrag_:0x4013355c0
# #RFCrag_RFCrag_:0x40132f980
# #RFCrag_RFCrag_:0x40132fc80
puts self # = #RFDocument:0x40161bfe0 # Correct I think, this is what I
expect
true
end
This one is called from a button_press(sender) method once the opened
document is on-screen, but the tableview is not populated. I would expect
this to be an RFDocument also.
def button_press(sender)
puts self # = ##Class:0x40049db20:0x4013e7680 # Incorrect? Or some
funny cocoa-generated subclass maybe?
end
I don't know what this object is, but it doesn't have the persistent store
set. Although I can then set it by calling a method from a menu that calls
the add_persistent_store(url) method, and make the document window display
the data.
Am I missing something? I've been banging my head against this one for hours
now. Any help is greatly appreciated.
