Zak:  you took this one, but I found the problem (same issue in the symbolizer)
... I won't fix it because you may have found it already, but the issue is in
the test

$nSelectedClass != null && $nSelectedClass > 0 && $nSelectedClass <
$oLayer->numclasses - 1

this should read

$nSelectedClass !== null && $nSelectedClass >= 0 && $nSelectedClass <
$oLayer->numclasses - 1

Note the double equals on the first condition, null is the same as 0 unless you
ask for 'exactly equals' ... so fixing the second condition doesn't work because
the first class (0) will fail on the first test until you make this change.
