Isnt it often the case. after 2 days of pulling your hair out. ask a question and bang the answer comes within 1/2 hour. So the secret is essentially cocoa bindings, and specifically <a href="https://developer.apple.com/library/mac/#documentation/cocoa/reference/ApplicationKit/Protocols/NSKeyValueBindingCreation_Protocol/Reference/Reference.html" rel="nofollow noreferrer">Key Value Bindings</a> That documentation is the typical yackademic yadda yadda. The cascading clue actually came from <a href="https://stackoverflow.com/questions/2961783/how-can-i-write-cocoa-bindings-as-code-instead-of-in-the-interface-builder">a similar stack overflow question</a> So all one needs to do is link the two controllers together like this. <pre><code>NSArrayController *source = [employeesWindowController employeeArrayController]]; NSObjectController *destination = [singleEmployeeWindowController employeeController]; [destination bind:@"contentObject" toObject:source withKeyPath:@"selection.self" options:nil]; </code></pre> The syntax follows that of the Interface Builder bindings. <pre><code>Bind to: Content Object Content Key: selection ModelKeyPath: self </code></pre> So its a darn easy one liner. Binding a <code>NSLabel</code> to a Controller. In IB <pre><code>Bind to: Value Content Key: selection ModelKeyPath: name </code></pre> In code, <pre><code>[label bind:@"value" toObject:controllerRef withKeyPath:@"selection.name" options:nil]; </code></pre> And the options mimic those of "Raises for Not Applicable Keys" and so forth. See yackademic text for the details.

Guidance

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.
