Greetings.I am attempting to set up an NSTableView with two columns, to represent a simple key-value store backed by two NSMutableArrays.Each of the arrays has an NSArrayController associated with it, and each of the columns is bound to one of the array controllers. However, when I add elements to each array, using the array controllers' add() method, the table shows only one value in both columns.With quite a bit of poking around (the full extent of which I fear I cannot recall), I was able to get it to change which value it displays in both columns, but I could not get it to display a different value in each column. NSLog() confirms that the correct values are being added to the arrays, so it's clearly a display issue of some sort.I've even created a table, array, and array controller purely for testing, and while the second table will display my test array's value properly, once I add a second column to the test table, bound to the first original array, both columns
