So before it happens, outlineView:objectValueForTableColumn:byItem: is being called regularly, and is returning my object (a file wrapper). Then when I click Revert in the dialog, I see reloadData called, then outlineView:objectValueForTableColumn:byItem: is called again, but this time the item is entirely unrelated to the outline view. And there shouldn't be an item at that stage. -- Shane Stanley <sstan...@myriad-com.com.au> 'AppleScriptObjC Explored' <www.macosxautomation.com/applescript/apps/> _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
