Greetings!

In my Core Data persistent document based application I have a need to open an existing data store on application startup as well as to allow saving any changes to the same original data store
I was able to implement the data loading part by programmatically establishing a managedObjectContext and passing it to the setManagedObjectContext method of my document.


It's not clear why you're adding a new context.


The challenge: After some changes have been made and a "Save" option is selected from the menu, the application prompts the user for a file name to save the data to. If the original file name is given then the application prompts to override the original file.
How can I change this behavior and enable my application to save changes to the original data store without overriding it.


I don't understand what you mean.
Do you want to add new data to an existing store but leave the original data intact?
Do you want to use two stores, one for each document, one shared global store?
Do you want some other configuration?
