sort is placing the values in $something_else::a and $something_else::b since it was called from package something_else. The workaround is to tell sort to pass the values as parameters by using the ($$) prototype:
sub fetSort($$) { # Prototype necessary.
my $ftA = $_[0]->{"fet"};
my $ftB = $_[1]->{"fet"};
$fetType->{$ftA} <=> $fetType->{$ftB}
}
package something_else;
sort netFetObj::fetSort @{ $OBJ->{"fets"} }
This negatively affects performance, according to the docs.
In the future, please use <c>...</c> around your code rather than (an unclosed) <pre>...</pre>, as per the Monestary Guidelines. A janitor will have to fix it for you.
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
