I want to use bindings to set certain control attributes (enabled state,
tool tip) depending on the number of selected rows in an outline table.
I have a controller object that owns an NSOutlineView, and I gave it
an accessor
- (NSOutlineView*) outlineView;
Then I tried to bind to my controller with key paths like
outlineView.numberOfSelectedRows and outlineView.selectedRowIndexes, and
using value transformers. It looks like the bindings are setting the
attributes appropriately once, but then not updating when the selection
changes. Are these NSOutlineView methods not KVO-friendly, or am I
doing something wrong?
