[Catalyst] info basic stash problem...maybe i am too tired this sunday

[Igor Longagnani]

As supposed i wastoo confused in my question, surely it wont get any
better ..anyway let's try :)

1) I am into a controller  and I have an hashref that  I punt into the
stash : $c->stash->{allegati} = $chiavi
2) in the template i wanna print out some of the values of the $chiavi
referenced hash
3) the values to printed out depend on keys which are built at runtime
inside the page template  ( lets pretend i take the keys from another
data structure )


now the question:

if $c->stash->{allegati} is a reference to a plain hash  (  e.g. 
{'3-bc-4' => 'alpha', ....,'t-rt-7' => 'omega'} ) and i have 1 key of
that hash in a variable of the page template, how do i print its hash
value ?

[% k % ]               # k = '3-bc-4'
[% allegati %]       # prints   HASH(0x2398423794 whatever)
[% allegati.k %]   # is nullor  doesnt work as i expected --->  how can
I print out 'alpha'?

I do beg your pardon for any miscomprehension due to my lack of
vocabulary or inesperience.
Thanks again for your already precious efforts in trying to understand
... :)

i.
