user.save(connection) causes a Null Pointer Exception

[jameswhite]

Expected Behavior

When creating a user and setting the authsrcid to one that exists on another user, I'd expect it to create a user, tell me why it didn't create. I would not expect a Null pointer exception to be thrown.

Current Behavior

Possible Solution

Steps to Reproduce (for bugs)

Run the code below

Ruby code that reproduces the issue:

#!/usr/bin/env ruby
require 'pp'
require 'nexpose'
include Nexpose

nsc = Connection.new(ENV['NEXPOSE_HOST'],ENV['NEXPOSE_USER'],ENV['NEXPOSE_PASS'],ENV['NEXPOSE_PORT'])
nsc.login
at_exit { nsc.logout }
roles = [ 'global-admin', 'security-manager', 'site-admin', 'system-admin', 'user', 'custom', 'controls-insight-only' ]

id = nil;
nsc.users.each { |user| id = user.id if user.name == "jameswhite" }
user = Nexpose::User.load(nsc,id)
pp user

puts

user = Nexpose::User.new("jayswan","Jay Swan", nil, roles[4], id=-1, 1, "[email protected]", all_sites = true, all_groups = true)
user.authsrcid = "1"
PP.pp user

result = user.save(nsc)
PP.pp result

exit

Output

Does your nsc.log from Nexpose show a stack trace for this? If so can you paste it here?
