[Catalyst] odd interaction between DBM::Deep::Hash and TT

[Daniel McBrearty]

Hi,

I'm posting this to the cat list and the TT list as it seems to be of
interest to both groups of users.

I have a hash which is made persistent with DBM::Deep. I pass the hash
straight through the controller to the template  (  $c->stash->{hash}
= $h; ), then iterate like this:

[%- FOREACH k in hash.keys -%]

<p> [%- k -%] </p>

[%- END -%]

I also dump the hash with $c->log->dumper in the controller, and see this:

[debug] $VAR1 = bless( {}, 'DBM::Deep::Hash' );

so I know an empty blessed hash is being passed.

But in the html out, I see :

<p> keys </p>

If I patch the controller so $c->stash->{hash} = {};

the problem goes away.

Is this some TT bug that interacts with DBM::Hash ? autovivifying
"keys" as a key not a function?

thanks

Daniel
