I would like to take an NSArrayController that is created from Core
Data and use the arrangedObject's (I do a lot of nested predicate
building to display only the desired values) to build a list of
distinct properties to be placed in a single column table.
For example, for a Core Data object consisting of people, I want a
separate table listing all _distinct_ first names (e.g. "John Smith"
and "John Doe" should result in a single listing of "John")
I was able to get the concept to work within a ComboBox by setting
the NSComboBox's content and contentValues to
email@hiddenName of my
NSArrayController (built from the Core Data).
It worked fine, but I don't want a ComboBox, I want a table. No
matter what I try, I cannot get the same functionality to work within
a table.
I have tried placing the @distinctUnionOfObjects bit in the table,
and in a new NSArrayController, and within a custom function within a
new subclass of NSArrayController, and am not making any headway.
I'm sure it's something simple but fundamentally different between
the needs of a ComboBox and a TableView.
Thanks to mmalcolm crawford for getting me this far, and thanks to
anyone who can point me in the right direction to getting a table
working.
