Using an array or hash reference as a default will probably not produce the
result that you might expect:
my @foo :Field
:Default({});
This does not result in a new empty hash reference being created for
each new object. Rather, a single empty hash reference is created when the
module is loaded, and then that reference is assigned to each newly created
object. In other words, it is equivalent to:
my %bar = ();
my @foo :Field
:Default(\%bar);
To get the other result, assign a new empty hash reference using an :Init
subroutine:
sub _init :Init
{
my ($self, $args) = @_;
$foo[$$self] = {};
}
This explanation will be part of the POD in the next release. Thanks.
BTW, OIO 3.08 is the latest version.
