I have an outline view with 2 entities being displayed inside it so It is connected to a NSTreeController. I have created a button and binded it to the NSTreeController's Controller Key 'canRemove' under Availability>Enabled. But when you run the App the button is always Disabled even when a row is selected in the Outline View. How can this be fixed to work and remove the selected row in the Outline view?

A:
You need to set the button's target to the tree controller, and its action to remove:. This is easy in IB: Right-click on the tree controller, then drag from its remove: action (specifically, from the circle at the right edge of the row) to the Remove button.

That looks right. What do you mean it “does not work”?

What I mean is that the button is disabled and will not allow you to click it.
