I have a document-based Core Data app that contains an entity with an attribute set to be an int16 in the data model.
I can set the value via the UI using bindings, and save it, but when I load that file back into the app, it crashes with an EXC_BAD_ACCESS error on the initialization of the array. Currently, I have that attribute set by a popup which is bound to an array in myDocument. The array is an array of NSString objects, and the indices are the numbers I want to associate with those strings.
In other words:
I have an NSArray which is declared in the myDocument header, and initialized in the myDocument -init method.
I have an NSArrayController that has its contentArray binding bound to that array.
I have the popUpButton's content bound to this NSArrayController (This works, the NSStrings appear in the popup).
I also have the selectedIndex bound to the entity's attribute, because I want the index to be the number stored in the entity's attribute.
(This also appears to work because when I change it and save it as an xml file, the saved file contains the proper number in the appropriate attribute)
However, when I load, it crashes in the init method of myDocument. There is nothing else in the init: method that was not there by default, other than creating the array.
I have no idea what is causing this, as I don't think I've violated any of the memory rules for Core Data apps. The bindings may be questionable, but they seemed to work. I have been trying to resolve this for several days and reading various docs and debugging hints, but I don't seem to be any closer.
Any insight would be appreciated.

PS: I asked about this before, but less clearly, so I am re-posting without the extraneous details.
