I'm using Cocoa bindings to manage an NSMatrix of switches (checkboxes) and the associated data. I've bound it's "content" to an array controller and it shows the correct number of checkboxes all with the correct titles. That works nicely.

The problem comes when I want to manage which are selected (checked) and which are not.

To do this I've bound the NSMatrix' "selectedObjects" to an object controller with the model key path of an array which contains a subset of the objects in the array which is used for the "content" array controller.

Is this the way I'm supposed to set it up?

In any case, the only result of configuring the "selectedObjects" binding that I can see is that the NSMatrix is completely disabled (greyed out, and non-responsive) in the Application.

Any ideas as to what's going wrong? Or does nobody else use bindings?

doh! How dopey can you get?

Of course the NSMatrix is disabled when there is no selection for the object controller from which it needs a selection. It's actually a fantastic feature that bindings does all this for me! Love it! Now when I actually make a selection, the NSMatrix becomes enabled, and I can selecte and deselect checkboxes to my hearts content.

BUT, it still isn't behaving correctly. Initially NO checkboxes are selected, and there should be some selected. Yet to figure out why this would be.
