Did you run your code? It doesn't even compile. And once I fix the compile error by changing
foreach $tmpvalue (@{$test{$key}{value})
to
foreach $tmpvalue (@{$test{$key}{values}})
it worked as expected.

obj1 --> 1
obj1 --> 2
obj1 --> 3
obj2 --> 4
obj2 --> 5
obj2 --> 6

Maybe if you showed us your real code, we could find the error.

In your real code, either

• $test{obj1} and $test{obj2} are references to the same hash, or
• $test{obj1}{values} and $test{obj2}{values} are references to the same array.

In other words, you have something equivalent to the following in your real code:

$test{obj1} = \%data;
$test{obj2} = \%data;

#    -or-
#
# $test{obj1}{values} = \@values;
# $test{obj2}{values} = \@values;


for($i=1;$i<4;$i++)
{
  push(@{$test{obj1}{values}},$i);
}

for($i=4;$i<7;$i++)
{
  push(@{$test{obj2}{values}},$i);
}
