I think you can bind to canRemove controller key, leaving model key
path empty.
Bind to: ArrayController
Controller Key: canRemove
Model Key Path: (empty)

Folks;
I would like to set some UI widget's enabled binding to whether or
not an array controller has any arrangedObjects.
If the arrayController has no current data then the widgets should
not be enabled.
Once the arrayController has some arrangedObjects then these widgets
should be enabled.
I can't seem to get the right settings for this in IB.
Do I have to create a method that returns a boolean or is there some
syntax for this directly in IB?
Bind to: ArrayController
Controller Key: arrangedObjects
Model Key Path: ???
Thanks for your help!
Steve
