Puppet users - Apr 2012 - hiera_array() default value not taken

Hi,

There is probably something stupid I am missing, but I just can''t see 
it. I do:

$iptables_open_ports_public = hiera_array
(''iptables_open_ports_public'', [])

And I have not defined that in the hiera tree, so the default (an empty 
array) should be returned. But I get, instead:

"Error 400 on SERVER: Could not find data item 
iptables_open_ports_public in any Hiera data file and no default supplied"

Is there any special way to define an empty array as a parameter?

Thanks!
Pablo

I have this problem too.  Do defaults work for anyone?

I''m using the YAML backend.  Not sure if that''s going to
matter.

Looks like a default of [] 
triggers
https://github.com/puppetlabs/hiera-puppet/blob/master/lib/puppet/parser/functions/hiera_array.rb#L32
to think that the `.lookup` function did not get an answer.

Hiera and Hiera-puppet have to distinguish between empty/false/nil answers 
sent by the backend due to missing data, or empty/false/nil answers 
explicitly returned as the default value or found value. Having hiera just 
return an empty answer when an answer is not found would probably not be 
preferable, so nil could possibly be the "not found" value?

I don''t think hiera likes defaults as array/hashes explicitly

I usually do a 

$empty_hsh = {}
$empty_arr = []

and use those as default values.

we end up doing this a lot:

$var = hiera_hash(''key'',''SOMESTRING'')
if is_hash($var) { 
....
}

not the most elegant
