I have made a simple program, that consists of an NSTableView that has columns that include text fields, sliders, and an Image view. I built it to make some simple experiments with Cocoa bindings, as I am learning them now. All are well, the new entries are properly handled, and I can change the imageview contents to any picture I like. The problem comes at the point where I quit the program. That's when the saving functions are called, and I am sure that I have done something wrong, because when I reopen the program (where the data should be automatically loaded), all I get are empty entries! Can anyone check the project? It's really simple and small. Any comment would be great.
