I believe that, as far as options go, Matt is referring to the binding
options that are present on the various bindings, rather than the
bindings available. There are about 10-12 of those, but their behavior
is somewhat dependent on the specific object to that exposes them.
Many of them are fairly self explanatory though, such as the
"Conditionally Sets" items, "Allows editing multiple value selection"
etc.
The biggest Mystery Option is the "Handle as Compound Value". I
believe (that is, I've not heard back from engineering) that when it is
off, the values for the key are accessed using either
valueForKey:/mutableArrayValueForKey: (which will return an array of
the keys at that keypath in the array i.e.
allTheFirstNames=[theUserData valueForKey:@"allTheUsers.firstName"].
If it is checked, then the indexed accessors are tried instead. Again
__I AM NOT 100% ON THIS BEHAVIOR__ (just want to make sure nobody
misreads that).
As I've said here a few times now, doc for the binding options is in
progress. I'll even go out on a limb and say that it's my top
priority. I can't, and won't, give a ship date - not even an estimate.
That'd just make it take longer, as I'd get in dookie.
