hi,
this SHOULD be automatic, if its a bug I'm guessing its WELL
documented, but no matter how well I search, I can't get ANY hits on
this. my application is Not Properly Loading my saved Core Data files.
I have a very simple Core data App.
it has 3 entities, two of them have relationships to the third.
category,
receipt,
and record.
as you can imagine, each record has both a receipt and a category
relationship, so that I can view my data along 2 axes.
the interface works great. everything works, adding new entities on
all levels, removing them, and changing their attributes.
but when I save the file, close it and re-open it... it appears to be
empty.
I've opened the file in a text editor, its NOT empty. I've had a good
look at the file after consecutive opens coupled with changes and then
saves.
the Objects Are Loaded, and forwarded to the next save, but my
arrayControllers IGNORE THEM!!!!
I thought that the array controllers might need to be set with a
filter predicate of either:
isRoot == YES, or
parent == nil
but those both have ZERO effect on this behavior. (and I can't find
the original references for those tricks)
anybody Know what is going on here? very similar apps I have built
work without ANY FUSS in this area whatsoever.
thnks,
-eblu
