Body
In retrospect, this answer seems somewhat obvious: I actually described 3 predicate editor row templates, not one. The three templates are: <ul> <li><code>dateKeyPath [<, <=, =, >, >=, !=] [NSDatePicker]</code></li> <li><code>dateKeyPath [inTheLast, notInTheLast] [NSTextField] [NSPopUpButton]</code></li> <li><code>dateKeyPath [between] [NSDatePicker] "and" [NSDatePicker]</code></li> </ul> If you build these three predicate editor row templates and give them to the predicateEditor, the editor will realize that they're all using the same <code>dateKeyPath</code>, and display then crunch all their operators into a single popup button. It will then switch out the actual views to the right of the operator depending on which operator is selected. Edit For bonus points: you can modify the precision of the date pickers by overriding the <code>templateViews</code> method, retrieving the templateViews from <code>super</code>, and setting the <code>datePickerElements</code> on the appropriate pickers. Edit 24 Nov 2010 For anyone who comes across this again, I've written a couple blog posts on creating custom <code>NSPredicateEditorRowTemplates</code>: <ul> <li><a href="http://funwithobjc.tumblr.com/post/1646098126/creating-a-simple-nspredicateeditorrowtemplate" rel="nofollow noreferrer">Creating a simple <code>NSPredicateEditorRowTemplate</code></a></li> <li><a href="http://funwithobjc.tumblr.com/post/1677163679/creating-an-advanced-nspredicateeditorrowtemplate" rel="nofollow noreferrer">Creating an advanced <code>NSPredicateEditorRowTemplate</code></a> (this one shows how to do the <code>inTheLast</code> and <code>inTheNext</code> row template)</li> </ul>

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.
