I just want to chime in again and report that MK at least makes it
very easy for me to compare the objects.
Based on my original example I can do:
var foo = {'item_no' : '185-N', 'name': 'Chair'};
var bar = {'item_no' : '185-N', 'name': 'Bed'};
arrayEqual(items(foo), items(bar)); // will tell you if they're equal.
Now I just gotta write the 'difference' code. :-)
Thanks,
Juergen
