BTW, loading and saving as seems to have some points in common with the second save as I mentioned in my previous email:
Load a file and Save As without making any changes:
a. Initializes a new atomic store
b. Reads from an empty file at the new save location within its temporary folder,
c. Saves to the same location (without creating any new cache nodes or updating from any managed objects)
d. Initializes another new atomic store
e. Loads from the file created just above
f. Creates a new cache node from my managed object (which populates from its managed object)
g. Saves the file again
Now this time, it appears that no clones are made of my managed object. I have not checked yet, but assume that the first load from empty file and save would just create a default blank document, and then the second load and save would actually populate it with data.
It very much appears that the behavior of the Save As command is dependent on something to do with the state of the managed object context and the persistent store, but I really haven't been able to figure that out yet, or what the impact is on my custom atomic store.
