    in my project I used core data and binding to produce data on document based program.
    I have used multiple entities and they worked fine and then they stopped working and I don't know why.
    all the text fields now have "()" in them with space in between them, and will not add to the database. so the field shows a junk value and will not bind properly to the database.

    how would I start to debug this I have been searching but I don't know where to start, mainly i dont know what the problem is.

    Presumably you're using a version control system, because everyone uses a version control system, right?

    Then compare your current version to a known good version and see what change broke your program.

    I was not using the version control however now I am for this reason.

    I figured it out though. The control key was changed for something else and never changed back it was arrangedObjects and needed to be selection.

    thank you for responding.

    Well, a Time Machine backup, or other regular backup, would also have served as a known-working reference.

    Or are you suggesting you have no regular backups?
