This is wrong. You should not create a cell view in this method, and you should not return a cell view as a result. The value returned from this method becomes the the "objectValue"  property of the cell view. Because you're trying to create the cell view in the wrong place, the table view is creating one for you (a different one), and that view isn't getting its text or image set to anything useful.

Instead, you should be putting the above code in a 'tableView:viewForTableColumn:row:' delegate method. Since you're (apparently) not using any bindings within your cell view, you don't need objectValue at all -- neither the data source method nor the property.
