Binding an NSNumber to an NSTableColumn
Hi, not sure what I'm doing wrong, or if this just isn't supposed to be done, but I'm having issues binding the value of an NSTablecolumn to an NSNumber through an Array Controller. When the document loads, it displays the values in the table properly, but whenever I try to select a row in this table, it crashes with EXC_BAD_ACCESS.
Now I tried changing the Key Path in the bindings window of the table column to add ".doubleValue", whereby I can select the row without it crashing, but then it changes all the numbers on that row to 0.
Another table view in the same app has NSUInteger and double values, and that one works ok, it's just when there's an NSNumber involved that it crashes. Are we not supposed to use NSNumbers for binding table columns? It seems like Apple is encouraging us to stop using primitives, so I find that highly unlikely. Anyone got any thoughts?
