Puppet users - Nov 2013 - custom type skip array element on munge

Hi all,

is there any way to completely ignore some array element when munging

custom_type { "name":
  groups => ["gr1", "gr2", "gr3"],
}

In case of any array member is not exists on system, I want to remove it
from resource[:groups]


But this code:

newproperty(:groups, :array_matching => :all) do

munge do |group|

  if does_not_exists(group)

    nil

  else

   group

  end

end


iterates on all array items and returns array with nil items. Is there way
to remove items from array in munge.


Thanks.
