This dont work. @{$c->error} or scalar @{$c->error} always print 0
in my debug screen.

$c->error is a arrayref or not?
So you must do this:
if( @{$c->error} ) {
...
}

Hi,all. Can anyone eplain me a bit about error handling. Where i
can catch it and when? I use this:
MyApp::C::MyController
sub auto : Private {
my ($self, $c) = @_;
if ($c->error) {
$c->stash->{error} = " Critical ERROR!! ";
$c->forward('/error');
$c->error(0);
return 0;
}
}
This works but then all my subs in this controller are redirected
to /error.

You need to create a sub finalize_error in your MyApp.pm to catch
errors. auto will happen before any errors take place, so of course it
will have nothing in it.
sub finalize_error {
my ($c) = @_; # Note, not ($self, $c)
if ( @{$c->errors} ) {
$c->stash->template('error.tt');
# You might also need to forward to the view here yourself
return;
}
$c->NEXT::finalize_error();
}
Something like that anyway - untested.
