Re: NSTableView and data cell formatter

[Fred Kiefer]

Hi Riccardo,

I did not look into the code here, but have a strong feeling what might go on 
here. Most likely your cells are editable, or at least selectable. And when 
they get selected, a different formatting method gets called that your specific 
formatter did not override. This may be editingStringForObjectValue:, but I am 
not sure. If the same code behaves correctly on Cocoa, we might have to look 
into the fallback code of NSFormatter.

Hope this helps,
Fred

On the road
