The problem is that you don't show where is_allowed_todo gets called. I
guess in the template as in your comment. The solution is very simple.
Change is_allowed_todo to change status in $object or elsewhere. Now
change the handler to do;
my $status = exists $object->{status}
? $object->{status}
: OK;
return $status;
does that solve your problem?
You return your status as the last thing in the handler, after the
template was processed, I don't see how can you have this problem
Even better solution would be to run is_allowed_todo from your code and
not template! Run is_allowed_todo, get the status and pass it to your
template as a variable.
One should avoid running code from the templates, as they are designed for
presentation not application logic.
