It is tied to the NSArrayController with a binding. If I edit the

Note that if I turn off "Auto Rearrange Content" it works ok, but then of
course after an edit, the filter does not "refilter" to reflect changes in
the data.
Note that I am only having this exception trouble with LevelIndicator
fields. Text fields work fine... If I change the text to fall outside the
predicate match, the row goes away without an exception being thrown.
