I'm stuck trying to understand a piece of NSOutlineView behavior. Perhaps I'm just missing the obvious solution, but I can't see it.
I have an view-based outline view configured as a source list. The list itself uses a data source, not bindings. The table cell view is a subclass of NSTableCellView, and subviews get their values via bindings. In short, it boils down to the standard text field being bound to TableCellView.objectValue.name. Instances of the table cell view are vended by 'outlineView:viewForTableColumn:item:' and the view's objectValue is set in that same delegate method. The column is marked "editable", and the text field does indeed permit editing.
Everything works, except for one thing. If I click on a text field to begin editing, type a few characters, then press Esc, then editing ends, but the text doesn't revert to what it was before editing began.
The changed value isn't committed back to the model, though it does persist as state within the outline view. (For example, hiding and re-showing the row shows the same incorrect value.)
I looked for the same behavior in the TableViewPlayground sample project, and it *does* revert the displayed value when you press Esc, but I don't see any code or configuration to support the behavior.
Anyone run into this before, or got a suggestion where to look for a solution?
