Are you inserting a copy of object into the array? If you do
ARRAY OBJECT($ao;2)
C_OBJECT($o)
OB SET($o;"property";$value)
$ao{1}:=$o
OB SET($o;"property";$newValue)
$ao{2}:=$o
you will end with one object referenced by 3 variables - $o, $ao{1} and
$ao{2}. If you tlater touch $o, both array elements will change (because
all point to the same object data.)
You need something like
ARRAY OBJECT($ao;2)
C_OBJECT($o)
OB SET($o;"property";$value)
$ao{1}:=OB COPY($o)
OB SET($o;"property";$newValue)
$ao{2}:=OB COPY($o)
