    <p>I've been trying to debug this for 2 hours, have to sleep. First, I've searched and found many similar posts with they keywords: many entities same type and this one: <a href="https://stackoverflow.com/questions/4985075/core-data-inverse-relationship-for-two-relationships-with-same-type">Core Data: inverse relationship for two relationships with same type</a></p> <p>But to no avail. Here's what's happening: I have a data model with two types. For example, I have a Person, and that person can have 4 lists of emails. The email type is its own thing, so I make the person store 4 distinct sets (relationships) to each list.</p> <p>Basically, when I retrieve one set, it grabs all of them. All 4 lists are now 1, and it doesn't seem to matter how I set the inverses. Actually these changes somehow caused the entire thing to not save anything, all nil objects when downloaded. Previous to this, it worked fine (except for shoving all 4 lists into one set). All I updated was the data model for relationships. I may have exported the files in the wrong order, but do not know if that's related.</p> <p>I simply can't find the keyword combination to find if someone's asked this before. I don't see how it wouldn't come up, what I'm doing is basic abstraction. I keep thinking I overlooked one box.</p> <p>To summarize, I have a person, and person has 2 lists. I add them similar to this: person.friendEmailsList = downloadedEmailsFromFriends; person.businessEmailsList = downloadedBusinessEmails;</p> <p>so later, I access person.friendEmailsList (using the correct core data call, of course), and instead of getting just friends, I get everything... friends, businesses everything</p> <p>Any suggestions would be appreciated</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
