Hey guys,
I'm really confused with the array controller and core data. I don't know what
I have to use to get what I want.
My program has for now a CollectionView which is populated by a core data fetch
request.
If I use an arrayController, I don't have to make this fetch do I?

I have a TableView and an ArrayController (no DataSource) and everything works
fine.
Clicking on a column header sorts my table ascending or descending.
But the order of the rows is totally wrong.
It seems that the ArrayController uses compare: to sort my strings.
The documentation rightly says
The windows's first responder will tell you if one of the table views has
focus. If there are other UI elements in the window which can have focus
though, this won't be good enough. Instead you'll have to start tracking the
first responder yourself and recording which table had it last

I'm ok with creating a special view for a simple value - that is, a

I'm not sure what the best way is to design a view that displays items

For the single item view, the view is based on three values that are
bound to the view. (eg: width, height, colour)
