We have a collection view, with its own nib and viewController, in a popover. Individual cells are modified clones of the prototype. The collection displays a list of controllers that depend on the main screen content. Opening the popover correctly shows all the relevant elements and controls work properly. The collection view is bound to an array controller which is bound to an array. However, if we leave the popover up and change the screen content (e.g. using a remote), the underlying array gets updated, but the change is not reflected in the collection view. Same result when we use a tear-off window. No collection view updates. The controls and the collection view go through the same binding path, so the path is not getting broken. We¹ve used collection views elsewhere and did not have this problem. Any theories as to what could cause this? _______________________________________________
