Hi all,

i try to add a hash to a dynamic dropdown, but for some reason this is not working, the dropdown receives <Script Error>
Compared the hash (values) to other working methods and they look identical(structure)

hash created from ssh.exec!(parameter).strip

{nil=>"-- Select --", "VG-CFME|lv_home"=>"VG-CFME|lv_home", "VG-CFME|lv_log"=>"VG-CFME|lv_log", "VG-CFME|lv_os"=>"VG-CFME|lv_os", "VG-CFME|lv_swap"=>"VG-CFME|lv_swap", "VG-CFME|lv_tmp"=>"VG-CFME|lv_tmp", "VG-CFME|lv_var"=>"VG-CFME|lv_var", "VG-CFME|lv_var_log"=>"VG-CFME|lv_var_log", "VG-CFME|lv_var_log_audit"=>"VG-CFME|lv_var_log_audit", "vg_pg|lv_pg"=>"vg_pg|lv_pg"}

other hash on working method
{nil=>"-- Select --", "dev"=>"DEV", "tst"=>"Test", "prd"=>"Production"}

if i set the hash not as var the dynamic dropdown get´s filled propperly
'values' => {nil=>"-- Select --", "VG-CFME|lv_home"=>"VG-CFME|lv_home", "VG-CFME|lv_log"=>"VG-CFME|lv_log", "VG-CFME|lv_os"=>"VG-CFME|lv_os", "VG-CFME|lv_swap"=>"VG-CFME|lv_swap", "VG-CFME|lv_tmp"=>"VG-CFME|lv_tmp", "VG-CFME|lv_var"=>"VG-CFME|lv_var", "VG-CFME|lv_var_log"=>"VG-CFME|lv_var_log", "VG-CFME|lv_var_log_audit"=>"VG-CFME|lv_var_log_audit", "vg_pg|lv_pg"=>"vg_pg|lv_pg"}

method get_lvs

require 'net/ssh'
require 'socket'

# Get IP from Hostname
def getIPAddress(name)
  begin
    IPSocket.getaddress(name)
  rescue SocketError
    false # Can return anything you want here
  end
end

# Remote SSH Access
def remoteSSHCommand(ipaddress, username, password, parameter)
  Net::SSH.start(ipaddress, username, password: password) do |ssh|
    ssh.exec!(parameter).strip
  end
end
begin
  # Default Variables
  hostname = $evm.root["dialog_param_input_fqdn"]
  ssh_user = $evm.object['ssh_user']
  # ssh_lvs_parameter > /usr/sbin/lvs --no-headings | awk '{print $2"|"  $1}' | uniq
  ssh_lvs_parameter = $evm.object['ssh_lvs_parameter']
  ssh_password = $evm.object.decrypt('ssh_password')
  # Value Hash
  values = {}
  values[nil] = "-- Select --"
  
  $evm.log(:info, "Hostname Response #{hostname}")
  ipAddress = getIPAddress hostname
  $evm.log(:info, "IPAddress Response #{ipAddress}")
  output = remoteSSHCommand ipAddress, ssh_user, ssh_password, ssh_lvs_parameter
  $evm.log(:info, "SSH Response #{output}")

  values[nil] = "-- Select --")
  output.each_line do |x|
    y = x.gsub(/\s+/, "")
    values[y] = y
  end
  
  $evm.log(:info, "HASH Response #{values}")  
  list_values = {
    'required' => false,
    'data_type' => "string",
    'values' =>  values,
    'default_value' => nil,
    'read_only' => false
  }
  list_values.each do |key, value| 
    $evm.object[key] = value
  end
end
exit MIQ_OK

the error i receive with this Method (evm.log)
