hmm... I dont consider this to be a bug...
here you create a global variable called 'gvar'
> $t->param(gvar => "global variable");
here you are creating a loop specific variable called 'gvar'
> { loopvar => "GVar should be set", gvar => "Loop GVar 1" },
These two 'gvar's are two different variables.
In this case
> { loopvar => "GVar should be blank again", gvar => undef },
you are saying that the loop specific 'gvar' is not part of the loop - ie equivalent
to:
{ loopvar => "GVar should be blank again" }
thus requesting the outer global gvar to come into scope.
Consider:
t->param(gvar => "Global gvar");
my $gvar_val;
my @loop;
for.... {
if (something) {
$gvar_val = "Loop GVar 1";
} elsif (somethign else) {
$gvar_val = "";
}
my $tmp;
$tmp->{loopvar} = ...;
$tmp->{gvar} = $gvar;
push @loop, $tmp;
}
t->param(testloop =>[EMAIL PROTECTED]);
What would you expect the TMPL_LOOP to do in that example?
I would have expected that the third iteration to use the global gvar value.
