It does work. I have defined a core data entity that conforms to

Are you doing the below plus bindings? That makes no sense to me.
The code below is using the array controller as its data source. That
means you have to manually use reloadData I assume. My goal is to
update a store of images that is KVO/KVC compliant and have the view
update automatically as images are added and removed.

- (int)numberOfItemsInImageBrowser:(IKImageBrowserView*)view
{
// The item count to display is the datadsource item count.
return [[imageBrowserArrayController arrangedObjects] count];
}

// imageBrowser:view:index:

-------------------------------------------------------------------------
- (id)imageBrowser:(IKImageBrowserView *) view itemAtIndex:(int) index
{
return [[imageBrowserArrayController arrangedObjects]
objectAtIndex:index];
}
// Implement some optional methods of the image browser datasource
protocol to allow for removing and reodering items.

// The user wants to delete images, so remove these entries from the
data source.

- (void)imageBrowser:(IKImageBrowserView*)view removeItemsAtIndexes:
(NSIndexSet*)indexes
{
[imageBrowserArrayController
removeObjectsAtArrangedObjectIndexes:indexes];
}

I am attempting to use bindings to supply an IKImageBrowserView

I have successfully used IKImageBrowserView with a data source, but
cannot
get bindings to work. Should it work with bindings?
The array controller's contentArray is hooked up to an NSMutableArray
called storedImages. That contains instances of storedImage. And
those have
a method browserObject that returns instances of an object that
implements
the IKBrowerItem protocol to fetch and display an image (uid, path,
etc).
The Image Kit browser is bound to the array controller's arranged
objects
with the model key path browserObject. It is set to automatically
prepare
content.
I get no images displayed even though there are plenty in the
storedImages
array. I am telling the browser view to reload its data.
If I set a breakpoint at browserObject, it is never hit. So it
looks like
the array controller is never attempting to read my model. I get no
errors
when loading my nib.
