[Catalyst] Using Jquery UI Autocomplete widget with Catalyst::View::JSON

[Hetényi Csaba]

Ahh!

That was the trick :)))
(expose_stash => 'json')

Now it is correctly translate the perl arrayref datastructure to JSON 
array ( [ ... ] )

my @aoh = (
     {
        value  => "1",
        label     => "betty",
     },
     {
        value => "2",
        label    => "jane",
     },

     {
        value => "3",
        label    => "marge",
     },
);
	$c->stash->{json} = \@aoh;
	$c->forward('View::JSON');

:)

Thanks Ben!

One last question: if I have a DBIx resultset, how to use it to
populate autocomplete with the easiest way?

Best wishes from Hungary!
