Re: refreshing core data controller



Thanks,

using fetch methods is what I usually do. In this case I want to use the controller because I want to set the UI as it was before managed context reset.

It means: I have a table with a couple of items and selection index is say 2. After reset selection index is always 0. I need to find the relevant item (by walking trough array controller) and set selection index to index of the item selected recently.

Perhaps I need just to postpone this action using -[NSRunLoop performSelector:] or similar...

Any other tips for some solution workaround?

Thanks

Pavel

My UI is refreshed fine but I'm having problems to access values via -[NSArrayController arrangedObject] right after I call reset on the managed context - arrangedObjects returns just an empty array.

It sounds like you're trying to treat your NSArrayController as part of your model. You should use Core Data directly -- execute fetch requests against your managed object context and so on -- from within model code. NSObjectController and its subclasses are intended to mediate between your model and your view layers, not to provide a way to manipulate your model directly.
