This probably won't work as expected because the array controller
(directly after your call to -insert:) won't be ready for you. From
the docs regarding -insert: ...
"Beginning with Mac OS X v10.4 the result of this method is deferred
until the next iteration of the runloop so that the error presentation
mechanism can provide feedback as a sheet."
Same goes for -add: ... You'll need to force the array controller to
-rearrangeObjects before asking the tableView to reload. If you're
using Core Data, you'll probably also need to force a -fetch: before
calling -rearrangeObjects, though I don't know for sure.
This forces the array controller to do its thing right then and
there. Of course short-circuiting the mechanism like that can cause
validation problems, so be careful ...
