using array parameters with inherited parameterized classes

[Shantanu]

I am trying to use an inherited array parameter in a parameterized
class as follows:

<puppet>
class params{
$packages = $operatingsystem ? {
Centos => ['scons','bzip2'],
Ubuntu => ['scons','bzip2'],
# Ubuntu => 'scons',
}
}

class depacks(
$packages = "$params::packages"
) inherits params {

package{ $packages:
ensure => 'present',
}
}

class {"depacks": }
</puppet>


* It's failing with following error:
<error>
err: /Stage[main]/Depacks/Package[sconsbzip2]/ensure: change from
purged to present failed: Execution of '/usr/bin/apt-get -q -y -o
DPkg::Options::=--force-confold install sconsbzip2' returned 100:
Reading package lists...
Building dependency tree...
Reading state information...
E: Couldn't find package sconsbzip2
</error>

* It works fine if I override the inherited array parameter while
calling/evaluating the class:
<puppet>
class {"depacks":
packages => ['scons','bzip2'],
}
</puppet>

I am using Puppet 2.6.14 with Ruby 1.8.7. The error occurs on both
Ubuntu and CentOS systems.

Am I missing something here? Any pointers will be really helpful.

Putting quotes around $params::packages is making $packages a string
rather than an array. Remove the quotes and it should work

Thanks for pointing it out Craig. It's working now.
